This document presents summaries of three phyllums from the animal kingdom: Pisces, Aves, and Mammalia. Pisces is divided into two classes: Chondrichthyes containing cartilaginous fish like sharks; and Osteichthyes containing bony fish like angler fish and lionfish. Aves includes birds with feathers and hollow bones, able to fly, such as peacocks, owls, and sparrows. Mammalia are mostly live-bearing and have hair, like kangaroos, porcupines, lions, and rhinoceros. Examples are provided for classes within each phyllum.

Sharks
There are almost 400 types of sharks that vary greatly in size, diet, coloring, and habitat. While most sharks live in saltwater, some can survive in freshwater. Sharks have cartilage skeletons and many rows of replaceable teeth. They are apex predators that play an important role in maintaining ocean ecosystems.
Crossopterygians
Crossopterygians were lobe-finned fish that lived during the Devonian period and are believed to have evolved into the first land vertebrates through their fin structure resembling tetrapod limbs. They had pectoral and pelvic fins with joint structures like tetrapod legs which evolved into the legs of early amphibians, and their skull structure also shows similarities to Devonian amphibians like Ichthyostega.
Education power point
The document provides descriptions of various ocean creatures including rays, whales, dolphins, squid, seahorses, sharks, octopuses, seals, jellyfish, and starfish. It discusses their physical characteristics such as appearance, diet, behavior, habitats and unique features. For example, it notes that rays have a boneless skeleton and feed on shellfish; whales are mammals that live entirely in water and communicate through singing; and octopuses can change color and squirt ink to evade predators.
Agnathan Fish Notes
The document discusses early fish evolution, including jawless fish like hagfish and lampreys. It describes key characteristics of hagfish, including that they have no backbone but are still considered vertebrates. It then discusses different classes of jawless fish like lampreys and ostracoderms, which were early armored fish. Placoderms followed as the first jawed fish.
Fish classification
This document provides an overview of fish classification systems presented by Nelson in 1984 and updated in 2016. It outlines the major taxonomic groups of fish, including jawless fish (hagfish and lampreys), cartilaginous fish (sharks and rays), and bony fish classified into ray-finned fish and lobe-finned fish. The updated 2016 classification separates hagfish from other fish and divides bony fish into two subclasses based on fin structure.
Evolution of fish (Early fish)
1. The document discusses the evolution of early fish according to the geological time scale. It describes important early fish species from the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous and Cenozoic eras.
2. Early fish evolved from jawless fish like Haikouichthys in the Cambrian period to jawed fish like Arandaspis in the Ordovician. Important jawed fish in the Silurian included spiny sharks and placoderms.
3. Diverse fish groups appeared in the Devonian period, including lobe-finned fish, sharks and armored fish
Whale evolution
The document outlines the evolution of whales from terrestrial mammals. It provides evidence from morphology, molecular biology, geochemistry, and the fossil record to support this. Key transitional fossils discussed include Pakicetus, Ambulocetus, and Basilosaurus, which show adaptations from land to fully marine environments over multiple steps of evolution. The conclusion is that with strong evidence from multiple fields of study, whale evolution from land to sea must be true.
Whale Evolution
The document summarizes the evolution of modern whales from their land-dwelling mammalian ancestors. It describes several key whale ancestors such as Pakicetus, Ambulocetus, and Rodhocetus that displayed adaptations like shorter legs and pelvises for swimming. Dorudon had tiny hind legs and could live off salt water, resembling modern whales. Modern whales are divided into toothed whales and those with baleen, both with tail flukes and underwater hearing abilities.

Class Actinopterygii and Class Sarcopterygii
This document provides information on ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). It describes their general characteristics such as habitat, locomotion, nutrition, and reproduction. It also covers their classification and anatomical features. Ray-finned fish make up over 50% of known fish species and contain familiar bony fish. They have flexible fins supported by bones. Lobe-finned fish were more abundant in the past and include lungfish and coelacanths. They have fleshy lobed fins and some can live on land.
Fish classification
The document classifies fishes and discusses the order Crossopterygii. Crossopterygii have internal nares, lobed fins except the first dorsal fin, scales with a cosmic layer, an air bladder that is lug-like, and a persistent notochord with unossified vertebrae. It also notes that Osteichthyes includes approximately 96% of all fish species.

General fish classification:- bony fishes and cartilaginous fishes.
Character of bony fishes and cartilaginous fishes...
Class osteichthyes <imran>
Fish are all members of the phylum Chordata, sub-phylum Vertebrata. Fish are generally spindle-shaped, oval in section, and flattened either sideways or dorsal-ventrally. The skin is covered in protective scales, with some exceptions (lampreys, ocean sunfish). All fins have fins of some sort, all the size, number, and shape vary. Fish breathe through gills, and only a very few have actual lungs. Most fish have a special organ known as a swim bladder that prevents them from sinking, and, in some cases, aids in respiration. The common name "fish" refers to four different classes, depending on the person classifying them (there are numerous different ways to classify fish). Bony fish also have special adaptations that allow them to remain buoyant. A special organ called a swim bladder housed under the bony skeleton is a gas filled chamber that allows the bony fish to remain floating in the water. Some fish have a connection between this organ and the digestive tract to allow the extraction of oxygen. Another special adaptation is the operculum, a flap on each side of the fish that covers the chambers housing the gills. A bony fish is able to breathe without swimming simply by moving the operculum. Other hallmarks of these fish are paired fins, many teeth, dermal scales in the skin (in most species), and numerous vertebrae. Most bony fish are ray-finned fish, meaning that they have thin, flexible skeletal rays. Lobe-finned fish, the other type of bony fish, have muscular fins supported by bones. Only one species of lobe-finned fish, the coelacanth, still lives. However, it was the lobe-finned fish that made possible the colonization of land.

Intro to Echinoderms Notes
The document discusses the phylum Echinodermata, which includes sea stars, sea urchins, sea cucumbers, and crinoids. Echinoderms are radially symmetric as adults and have a water vascular system instead of a circulatory system. This water vascular system allows them to move, feed, and exchange gases via tube feet that extend from their bodies. The four classes of echinoderms are discussed: Asteroidea (sea stars), Echinoidea (sea urchins), Holothuroidea (sea cucumbers), and Crinoidea (crinoids/sea lilies).
Class Osteichthyes (Bony Fishes)
The class Osteichthyes includes all fish that have bones in their skeletons. It is the largest class of vertebrates currently existing. Osteichthyes have skeletons made of bone, scales, bony opercula covering the gills, and lungs or swim bladders. They are primarily cold-blooded. The class is divided into two subclasses: Actinopterygii, which includes the ray-finned fishes that have fins without muscles lobes; and Sarcopterygii, which includes the lobe-finned fishes that have muscular lobes associated with their fins and usually use lungs for gas exchange.
Classification of fishes
Classification of Fishes can be summarized as follows:
1. Fishes are classified based on their anatomical features and placed in a systematic hierarchy ranging from superclass to species. Some key groups include chondrichthyes (cartilaginous fishes like sharks), osteichthyes (bony fishes), actinopterygii (ray-finned fishes) and sarcopterygii (lobe-finned fishes).
2. Important historical schemes for classifying fishes were proposed by scientists such as Berg in 1940, who grouped fishes based on characteristics like jaw structure, fin morphology, scale type and vertebral structure.
3. Major fish groups discussed in
Fishes
Fishes are the most ancient group of vertebrates, first appearing 530 million years ago. They are highly diverse with over 28,000 living species. Fishes are aquatic and have adapted various anatomical features for aquatic life including scales, fins, buoyancy control and efficient gill respiration. Major groups include jawless fishes, cartilaginous fishes like sharks, and bony fishes including the dominant ray-finned fishes and rare lobe-finned fishes like lungfishes and coelacanths.
Comp.ana. ostracoderms,acanthodians,placoderms
The document describes several groups of ancient jawed and jawless fishes:
- Ostracoderms were the oldest known craniates, dating back to the Ordovician and lacking jaws and paired fins.
- Acanthodians were early jawed fishes with cartilaginous skeletons and bony scales or spines.
- Placoderms were the first armored fishes with true jaws, some reaching large sizes. They are divided into orders including Arthrodira with jointed armor, Antiarchi with enclosed pectoral fins, and Petalichthyida typified by splayed fins.
Hammerhead sharks
Hammerhead sharks are distinguished by their hammer-shaped heads. There are eight species that inhabit coastal waters around the world to depths of 300 meters. They are highly social and communicate through body movements. Hammerheads have wide-set eyes and nostrils on their hammer-shaped heads which help them hunt prey like fish, sharks, stingrays, and invertebrates. Their unusual head shape provides maneuverability for restraining prey. Overfishing threatens hammerhead populations due to their slow reproduction rates.
Power jorge-rubio
Most reptiles lay eggs and live in various habitats. There are many types of reptiles that can be found in the air, on land, and under the sea. Reptiles like lizards and crocodiles have distinguishing features such as scales, claws, and large teeth.
Hammerhead Sharks
Hammerhead sharks live in tropical and temperate coastal waters, preferring warm seas and sea beds, and eat a variety of fish, rays, crabs, and squid while their only predator is humans. They are distinguished by their gray-brown or bronze coloration, small jagged teeth arranged in triangular rows, and their scalloped "hammer" shaped heads that can reach 10 to 12 feet long and help them sense prey through electrical signals and use their wide-set eyes to see better.
Fish
Fish are cold-blooded aquatic vertebrates that breathe through gills and have fins and scales covering their bodies. They live exclusively in water and extract oxygen from water through their gills. While most fish are ectothermic, one type of fish, the opah or moonfish, has been discovered to be warm-blooded. It generates its own body heat through rapidly flapping fins. Ichthyology is the scientific study of fish, of which over 34,000 species have been identified worldwide, with the majority living in oceans.
Aquatic mammals and their adaptation, General Feathers of Aquatic mammals
Aquatic mammals have adapted to live fully or partially in water. Some mammals, like whales and dolphins, live their entire lives in water. Others, like seals and otters, spend most of their time in water but need to return to land for activities like mating. Adaptations for aquatic life include streamlined bodies, webbed limbs or flippers, large lungs and nostrils placed high on the head. Examples of fully aquatic mammals are whales, dolphins and manatees. Semi-aquatic mammals include seals, otters and hippopotamuses.
Brachiopods
Brachiopods are marine invertebrates that live in oceans worldwide. They have two shells or valves and a coiled feeding organ called a lophophore. There are two major groups - articulate brachiopods which have teeth and sockets that join the valves, and inarticulate brachiopods which rely on muscles. Brachiopods have been around for over 500 million years and their fossils provide clues about ancient marine environments, though there are fewer living species today.

Chordata gnathostomata: TAXONOMY: T. Y. B.Sc. Zoology, Sem. VI; Course Code-U...Dr. Sudesh D. Rathod, B N Bandodkar College of Science
Chordata is an assemblage of heterogeneous animals which differ widely in their characteristics but have a few common features like they have notochord, dorsal tubular nerve cord, pharyngeal gill slits and post-anal tail. The notochord is a cartilaginous skeletal rod present at some stage in their life cycle. Nerve cord is mid-dorsally placed and is hollow containing axial nerve canal. Pharynx is perforated containing several gill slits primarily were used for filter feeding but later evolved as respiratory in function in aquatic forms.However, in terrestrial forms they disappear in adults but are occurred in embryonic stages. The body extends beyond anal terminal to give rise to a balancing or important part in locomotion called as tail.Moray Eel
Moray eels are tropical fish found in coral reefs and rock crevices in saltwater environments. They range in length from 11-400 cm and can weigh up to 30 lbs. Moray eels have a long dorsal fin and two sets of sharp, backwards-pointing teeth. They breed in spring and summer by wrapping their bodies together while releasing eggs that are fertilized and float until developing into larvae and then eels. Moray eels have been around in their current form for 5-23 million years according to fossils.

It outlines eight key methods of fish taxonomy: 1) by scientific naming conventions, 2) physical traits measured, 3) evolutionary lineage, 4) presence of jaws or not, 5) bone structure, 6) habitat salinity tolerance, 7) position in the water, 8) migratory behavior, and 9) feeding behavior. The taxonomy of fish involves categorizing them into groups based on observable shared characteristics.
Classification-of-fishes.pdf
The document discusses the classification of fishes throughout history. It describes early classifications by Muller, Berg, and Romer, which divided fishes into 6, 7, and 4 classes respectively. The current and most widely accepted classification is Nelson's from 1994, which uses a cladistic approach and evolutionary relationships to arrange fishes into subclasses under the subphylum Vertebrata. Nelson's classification places fishes in the grade Pisces and divides them into classes like Placodermi and Osteichthyes.

This document is a PowerPoint presentation by Soumyadeep Saha Mondal, a student at Ramakrishna Mission Vivekananda Centenary College, on the study of two non-chordate animals - the Giant Pacific Octopus and the Cannonball Jellyfish. It provides details on the morphology, locomotion, digestive system, respiratory system, excretory system, reproduction, nervous system of the Giant Pacific Octopus. For the Cannonball Jellyfish, it describes the morphology, locomotion, digestive system and notes that it does not have well-developed digestive, respiratory, nervous or excretory systems. It also mentions that Cannonball Jellyfish stings can cause pain
DIVERSITY IN LIVING ORGANISMS
Classification systems help organize the diversity of life on Earth. Early systems like Aristotle's grouped organisms by habitat, but this was misleading as very different organisms can share a habitat. Modern classification is based on fundamental characteristics like cellular structure, multicellularity, and mode of nutrition.
The five kingdom system proposed by Whittaker in 1969 divides organisms into Monera, Protista, Fungi, Plantae, and Animalia. Carl Woese later divided Monera into Archaebacteria and Eubacteria. Organisms are also classified as eukaryotes or prokaryotes based on cellular structure. Vertebrates like fish, amphibians, reptiles, birds and mammals are classified based on

This document provides information about two non-chordate animals in a PowerPoint presentation: the Giant Pacific octopus, a coelomate animal, and the Cannonball jellyfish, a non-coelomate animal. It describes their morphological features, locomotion, digestive and other body systems. Key details provided include the Giant Pacific octopus' large size of up to 30 feet arm span, jet propulsion locomotion, and the female's protective care of her large clutch of 18,000-100,000 eggs for 6 months. For the Cannonball jellyfish, its dome shape up to 25cm wide and movement by pulsating its bell are highlighted.
CLASSIFICATION OF FISHES in details all describe
The document discusses the classification of fishes according to J.Z. Young in 1981. It describes the two main groups of bony fishes - ray-finned fish and lobe-finned fish. Ray-finned fish, known as Actinopterygii, are the largest vertebrate clade comprising over 24,000 species. The document then provides details on the different classes of fishes including Placodermi, Chondrichthyes, Osteichthyes, and subclasses within Osteichthyes. It outlines key features used for fish classification including endoskeletal structure, exoskeletal features, fin patterns, tail type, and more. Classification of fishes is based on
Mollusca of India and need for conservation
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species

Unit 25 Vertebrates
All vertebrates share four key characteristics - a notochord, hollow nerve cord, pharyngeal slits, and tail - at some stage of development. While most lose these traits as adults, they define the phylum Chordata. Vertebrates evolved internal skeletons allowing them to grow larger and more complex, with jaws developing from gill arches, giving them predatory advantages. Major vertebrate groups include fish, amphibians, reptiles, birds and mammals.
Parasites metazoan (cestode, nematode,acantho)
This document provides information on various phyla of parasites found in fish, including Platyhelminthes (cestodes and trematodes), Nematoda (nematodes), and Acanthocephala (thorny-headed worms). It describes their basic morphology, lifecycles, examples of types of parasites, and the pathology they can cause in different types of fish hosts. Common parasites discussed include tapeworms, flukes, roundworms, and spiny-headed worms.
Gnathostomata
Introduction
Gnathostomata are the jawed vertebrates. (gnathos= "jaw" + (stoma)="mouth".
It comprises roughly 60,000 species. (99% of all living vertebrates).
Living gnathostomes have teeth, and paired appendages.
A horizontal semicircular canal is present in the inner ear.
Myelin sheaths is present on the neurons.
Adaptive immune system uses V(D) J recombination ( it is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. VDJ recombination is the process by which T cells and B cells randomly assemble different gene segments – known as variable (V), diversity (D) and joining (J) genes – in order to generate unique receptors (known as antigen receptors) that can collectively recognize many different types of molecule. While Agnatha (petromyzon and hagfish) use genetic recombination in the variable lymphocyte receptor gene.
It is now assumed that Gnathostomata evolved from ancestors that already possessed a pair of both pectoral and pelvic fins.
In addition to this, some placoderms were shown to have a third pair of paired appendages, that had been modified to claspers in males and basal plates in females—a pattern not seen in any other vertebrate group.
It is believed that the jaws evolved from anterior gill support arches that had acquired a new role, being modified to pump water over the gills by opening and closing the mouth more effectively – the buccal pump mechanism.
Presence of Calcified, bony skull and vertebra are the characteristic features of Gnathostomata (fishes, amphibians, reptiles, birds and mammals).
Pelvic fins are situated just in front of the anus.
Interventrals and basiventrals present in the backbone. These are the elements of the backbone which lie under the notochord, and match the basidorsals and interdorsals respectively.
Gill arches which lie internally to the gills and branchial blood vessels, contrary to the gill arches of all jawless craniates, which are external to the gills and blood vessels.
A horizontal semicircular canal in the inner ear.
Paired nasal sacs which are independent from the hypophysial tube.
There are numerous other characteristics of the soft anatomy and physiology (e.g. myelinated nerve fibres, sperms passing through urinary ducts, etc.), which are unique to the gnathostomes among extant craniates, but cannot by observed in fossils.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
