Phylum coelenterata
This document summarizes key characteristics of cnidarians. It describes their three classes - Hydrozoa, Scyphozoa, and Anthozoa. Cnidarians are radially symmetric and have specialized cells. They live in water and have tentacles covered in stinging nematocysts that help capture prey. They reproduce both sexually and asexually, and different classes display different forms like polyps or medusae and move via jet propulsion or crawling.
Phylum Mollusca
This document summarizes the characteristics of the phylum Mollusca. It describes their soft unsegmented bodies, bilaterally symmetrical structure, and hard calcareous shells. It divides the body into a head, mantle, visceral mass, and foot. It provides details on their digestive, respiratory, circulatory, excretory, and nervous systems. It lists the six major mollusc classes and provides one example for each: Monoplacophora, Amphineura, Scaphopoda, Gastropoda, Pelecypoda/Bivalvia, and Cephalopoda.
Cnidaria phylum
Cnidaria is a phylum containing over 9,000 species found only in aquatic and mostly marine environments. All cnidarians have radial symmetrical. There are two major body forms among the Cnidaria - the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae.
Lecture 4 coelentrates and cnidarians
Cnidarians are a phylum of aquatic animals that include jellyfish, corals, sea anemones and hydroids. They are radially symmetrical with a mouth surrounded by tentacles, and have stinging cells called nematocysts. Many cnidarians alternate between sessile polyp and motile medusa body forms. Their body wall is composed of two tissue layers with a jelly-like mesoglea in between. They have a nerve net and gastrovascular cavity for digestion and gas exchange. The five classes are Hydrozoa, Scyphozoa, Staurozoa, Cubozoa and Anthozoa.
Aschelminthes
This document provides an overview of the phylum Aschemlinthes. It discusses their key features including their cylindrical body shape without segmentation, bilateral symmetry, triploblastic germ layer, and tube within tube organ system level of organization. Their body wall has a cuticle, epidermis, and longitudinal muscle layers. They have a pseudocoel body cavity and hydrostatic skeleton. Their digestive system is complete with a mouth, pharynx, intestine, and anus. Respiration occurs through the body surface and circulation is undeveloped. Their nervous system includes a circum pharyngeal ring and sensory structures. Excretion involves protonephridia. Reproduction involves separate sexes with internal fertilization and mostly
Echinoderms
The document summarizes the five classes of echinoderms: Asteroidea (starfish), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Holothuroidea (sea cucumbers), and Crinoidea (sea lilies). It describes the key characteristics of each class, including their anatomy, physiology, reproduction, and distinguishing features. The classes are defined by attributes such as number of arms, presence of a central disc, tube foot structure, feeding method, and whether they are sessile or mobile.
Cnidarians
Phylum Cnidaria includes jellyfish, corals, hydras and other organisms. They have simple diploblastic bodies with radial symmetry. They possess stinging capsules called cnidocytes that aid in defense and prey capture. Their bodies include a gastrovascular cavity with one opening that functions as both a mouth and anus. They exist either as polyps, which are cylindrical and attach to substrates, or medusae, which are bell-shaped and float freely. Some alternate between these forms while others possess only one. The four main classes are Hydrozoa, Scyphozoa, Cubozoa and Anthozoa, which differ in their predominant life stages and habitats.
Phylum Annelida
The document discusses the phylum Annelida, or segmented worms. It describes their characteristics, such as being hermaphroditic and having a true coelom. It then discusses different classes of annelids, including Polychaeta (marine fanworms and free-swimming worms), Oligochaeta (earthworms), and Hirudinea (leeches). For earthworms specifically, it outlines their movement, excretion, digestion, respiration, circulation, response, and reproduction systems.

Coelenterata general characters & classification
Coelenterata is a phylum of aquatic animals that includes jellyfish, corals, sea anemones and hydroids. They are diploblastic with two main cell layers, a gelatinous mesoglea in between, and stinging nematocysts. They exhibit radial or biradial symmetry and polymorphism. Reproduction can occur asexually through budding or sexually through external fertilization and a planula larva stage. The phylum is divided into three classes: Hydrozoa, Scyphozoa, and Anthozoa.
Phylum echinodermata 2016
Phylum Echinodermata includes sea stars, sea cucumbers, brittle stars, sea urchins, and sand dollars. They are radially symmetrical with a pentamerous body plan and have a water vascular system and endoskeleton. The phylum contains four classes: Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), and Holothuroidea (sea cucumbers). Echinoderms are found on the ocean floor and have tube feet, spines or plates, and can regenerate lost body parts. Their water vascular system is unique and used for movement, structure, and respiration.

Pentaceros is an echinoderm, ie spiny skin organism, It is remarkably known for its five arms and regenerative capabilities, the presentation discusses various aspects of its nomenclature, taxonomy, biology including feeding, reproduction, development, ecological significance. It has direct similarities to the most primitive chordates the hemichordates during their development hence play an integral role in the evolution story as a connecting link.
Chaetognaths, echinoderms, and hemichordates
This document describes the phyla Chaetognatha, Echinodermata, and Hemichordata. It provides details on their body forms, characteristics, classes, and examples. Some key points include: Chaetognaths are small marine arrow worms that are predators of plankton. Echinoderms have a calcareous endoskeleton and pentaradial symmetry, and include sea stars, sea urchins, sea cucumbers, and sea lilies. Hemichordates are small marine bottom dwellers that possess gill slits and a rudimentary notochord, and include acorn worms and colonial pterobranchs.
Molluscan
Cephalopods such as octopuses, squid, and cuttlefish evolved large brains, complex senses, and rapid locomotion for predation, but their numbers have declined dramatically. Vertebrates may have outcompeted cephalopods by developing active predatory lifestyles. Mollusks are a large phylum that includes snails, slugs, mussels and octopuses. They have soft bodies that are sometimes covered by an external shell secreted by the mantle. Mollusks display bilateral symmetry and their body plans generally include a head-foot region and visceral mass.

Cnidarians
The document discusses the phylum Cnidaria, which includes animals like hydra, jellyfish, coral, and sea anemones. Cnidarians have radial symmetry, a gastrovascular cavity for digestion, and stinging cells called nematocysts. They can be either solitary polyps attached to the sea floor or free-swimming medusae. Corals secrete calcium carbonate cups and form coral reefs in warm, salty waters. Jellyfish are free-swimming cnidarians with an umbrella-shaped body.
13. class hydrozoa with clear explanation only on slide share free
Hydrozoans are a class of cnidarians that can live in both marine and freshwater environments. Most hydrozoans display alternation of generations, alternating between a polyp stage and a medusa stage, though some lack one stage. Obelia is a common marine hydrozoan that forms colonial polyps connected by a shared gastrovascular system. Its polyps specialize into gastrozooids for feeding and gonzooids for reproducing by budding off small medusae. Gonionemus is a hydrozoan where the medusa stage predominates, using jet propulsion and statocysts for swimming and navigation. Hydra is a freshwater hydrozoan lacking medusae; it reprodu
PROTOTHERIA.pptx
The document discusses the characteristics and phylogenetic relationships of prototheria, the subclass of primitive egg-laying mammals. It notes that prototheria include monotremes like the platypus and echidna, which lay eggs but nourish their young with milk. While prototheria share some traits with reptiles like claws and an interclavicle bone, they also share traits with mammals like fur, mammary glands, and a four-chambered heart. The document outlines the anatomical features and development of prototheria in detail.
Echinoderms (Echinodermata)
There are main 5 classes of living echinoderms:
crinoids (sea lilies and feather stars); asteroids (STARFISH); ophiuroids (brittle stars); echinoids (SEA URCHINS, etc); and holothuroids (sea cucumbers).
Echinoderms have been well preserved as FOSSILS; all existing classes and several others now extinct were present in the Ordovician (505-438 million years ago). They may have originated in the Precambrian (over 570 million years ago).
Common name : sea lilies, Sea Stars(STARFISH), sea urchins, sea cucumbers, and brittle stars.
Habitat
Echinoderms occupy all habitats including coral reefs, mangroves, seagrass and soft-bottom areas.
Except for a few species which inhabit brackish waters, all echinoderms are benthic organisms found in marine environments. Echinoderms inhabit depths ranging from shallow waters at tide lines to the deep sea.(Barnes, 1987; Brusca and Brusca, 2003; University of Alabama Center for Communication and Educational Technology, 2000; Waggoner, 1999)
Habitat Regions
• temperate
• tropical
• polar
• saltwater or marine
Aquatic Biomes
• brackish water
Other Habitat Features
• intertidal or littoral
GeoGraphy and eco-system
Geographic Range
Mainly a marine group, echinoderms are found in all the oceans. (Brusca and Brusca, 2003)
BIOGEOGRAPHIC REGIONS
• arctic ocean
• indian ocean
• atlantic ocean
• pacific ocean
• mediterranean sea
Eco-system
Sea urchins are among the main herbivores on reefs and there is usually a fine balance between the urchins and the kelp and other algae on which they graze. A diminution of the numbers of predators (otters, lobsters and fish) can result in an increase in urchin numbers causing overgrazing of kelp forests with the result that an alga-denuded "urchin barren" forms.
Work cited:
Lawrence, J. M. (1975). "On the relationships between marine plants and sea urchins". Oceanographic Marine Biological Annual Review 13: 213–286.
Ecosystem Roles
Echinoderms are usually intricate parts of their ecosystems. Many asteroids are keystone species. Sea urchins, if not controlled by predators, may overgraze their habitat. Asteroids have several commensals, including polychaetes that feed on leftovers from the sea star's prey items. (Barnes, 1987; Brusca and Brusca, 2003)
Ecosystem Impact: keystone species
Annelida
Annelids are segmented worms belonging to the phylum Annelida. They have a soft, elongated cylindrical or flattened body divided into many segments. Their body plan involves a hydrostatic skeleton, a complete digestive tract, a closed circulatory system with blood vessels and fluid-filled coelom. They respire through their skin or gills, excrete through nephridia, have a nerve cord with ganglia, and can reproduce both sexually and asexually. Annelids display regeneration and some have a trochophore larval stage.
Phylum Echinodermata Presentation
Echinoderms are marine invertebrates with a pentaradial symmetry as adults and a water vascular system. They include sea stars, sea urchins, sand dollars, brittle stars, sea cucumbers, and sea lilies. The document describes the key characteristics, anatomy, lifecycles, and functions of the five classes of echinoderms.
Coelenterates- The Obelia
Obelia is a colonial marine cnidarian that exists in both a sessile polyp stage and a free-swimming medusa stage. It has a branching structure made of hydrocaulus and hydrorhiza that support gastrozooids for feeding and gonozooids for asexual reproduction. Gonozooids bud numerous small medusae that detach and transition Obelia to its sexual medusa phase, where it reproduces sexually to complete its life cycle.

Reproduksinya melalui aseksual pada polip dan seksual pada medusa. Terdiri dari hydrozoa, scyphozoa, dan anthozoa.
9. Phylum Porifera Notes
Phylum Porifera includes about 5,000 living species of sponges. There are three main classes: Hexactinellida (glass sponges), Demospongia (most diverse class making up 90% of species), and Calcarea (found in shallow waters with calcium carbonate spicules). Sponges are the most primitive multicellular animals and feed by filtering water through their outer walls using flagella and contractile cells to pump water in and out for feeding, waste removal, and oxygen intake. They reproduce both sexually and asexually.

- Major phyla discussed include porifera, cnidaria, platyhelminthes, nematoda, annelida, arthropoda, mollusca, echinodermata, protochordata and vertebrata.
- Vertebrata is further divided into classes of pisces, amphibians, reptilia, aves
Coelenterata
1. The document describes the phylum Cnidaria, focusing on the class Coelenterata.
2. Coelenterata have a radial symmetrical body plan with two tissue layers (ectoderm and endoderm) separated by a jelly-like mesoglea. They exist in polyp and medusa forms.
3. Coelenterata are carnivorous, using stinging cells called cnidocytes on their tentacles to capture prey. They reproduce both sexually and asexually.
cnidera
Phylum Cnidaria includes jellyfish, sea anemones, corals and hydroids. They have radial or biradial symmetry, nerve nets, and use nematocysts for defense and prey capture. Their life cycles often involve both polyp and medusa stages. Phylum Ctenophora includes comb jellies which have colloblasts for prey capture and comb rows for swimming. They lack nematocysts and a polyp stage.
Coral taxonomy
This document provides information on the taxonomy of corals. It begins by introducing the phylum Cnidaria, which includes corals. It then describes key characteristics of Cnidaria and provides a classification system, dividing the phylum into four classes: Hydrozoa, Scyphozoa, Anthozoa, and Cubozoa. Most of the document focuses on describing the class Anthozoa, which contains corals and is further divided into subclasses and orders. For each group, example genera are provided. Key characteristics and taxonomic groups of important soft coral orders are also summarized.

It also discusses coral reef ecology and threats to corals from factors such as warming oceans, acidification, and pollution.
Phylum Porifera: The Pore Bearing Animals
Phylum Porifera includes sponges, the simplest multicellular animals. They live in both freshwater and marine environments and have no true tissues. Their bodies are composed of totipotent cells and a skeleton made of silica or calcium carbonate spicules. Sponges filter feed using flagellated cells and circulate water through their porous bodies via an aquiferous system. They reproduce both sexually through external fertilization and asexually by budding or gemmules. Many species have symbiotic relationships with bacteria and algae. Sponges provide important habitat and are a source of bioactive compounds used in human pharmaceuticals to treat diseases.
A survery of kingdom animalia
Chordates are classified into 3 subphyla: Cephalochordata, Urochordata, and Vertebrata. Cephalochordata and Urochordata are invertebrates while Vertebrata includes fish, amphibians, reptiles, birds, and mammals. All chordates share structures like a notochord, dorsal nerve cord, pharyngeal slits, and postanal tail. The subphylum Urochordata includes tunicates that are marine filter feeders while Cephalochordata includes lancelets that have elongated segmented bodies and retain their notochord. Vertebrates are distinguished by having a head, brain, vertebrae,

Relationship of qualitative and quantitative fisheries diversity with the environmental variables was studied for the period of two years along the three zones, viz. upper, middle and lower, of the Ulhas River estuary. Total ten hydro-sedimentological parameters were analyzed on monthly basis from each zone to depict ambient pollution level. Zones with comparatively higher pollution level deterred fisheries landings. The principal coordination analysis (PCO) ordination and zonewise K-dominance curves revealed the direct correlation of fish diversity with the existent spatial environmental conditions of the Ulhas River estuary.

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.Basic boat building techniques: A Fisheries Science
Basic boat building techniques: A Fisheries ScienceDr. Sudesh D. Rathod, B N Bandodkar College of Science
A hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline.
The gunwale is a nautical term describing the top edge of the side of a boat.
The bow is a nautical term for the forward part of the hull of a ship or boat, the point that is most forward when the vessel is underway.
The opposite to the bow of boat is called the stern.
A deck is a permanent covering over a compartment or a hull, which forms the 'roof' for the hull, which both strengthens the hull and serves as the primary working surface.
The mast of a sailing vessel is a tall, vertical or near vertical spar, or arrangement of spars, which supports the sails.Boat foulers and borers: Fisheries Science
Organisms in the water, especially saltwater, attach to slick surfaces like a boat's hull. It doesn't take long for a boat hull to become slimy with algae. Algae pave the way for adherence of other organisms. The general term for organism on a boat hull is fouling. Fouling makes boats drag, use more fuel and harder to maneuver. Invasive organisms spread by hitching a ride on the underside of a boat. Common marine foulers include barnacles, algae, shellfish, tunicates, ship-
worms, gribbles etc.
Wood borers are highly specialised animals which penetrate wooden structures such as boats, wharves, jetties, driftwood and even living mangrove trees. Many can digest the wood owing to cellulose-digesting bacteria or protozoa living in their guts. Only a few species can actually produce their own cellulose-digesting enzymes (cellulases).Wood borers are insects that chew their way into the solid trunk of a living tree or into a wooden structure, such as an old boat or house. Healthy trees are rarely attacked by wood borers, but a diseased or dying specimen can often host these kinds of invaders. The same goes for old houses and boats, where rain-soaked or rotten wood is more susceptible to invasion.

Non-conventional fishing methods:
light fishing; hose pipe fishing; electric fishing.
Pelagic (surface/open ocean) gillnets are systems of netting with highly specific mesh sizes. Gillnets as long as 2.5km, are placed vertically in the water column with the use of buoys and weights. These nets may be anchored or allowed to drift with prevailing currents, intercepting migrating sharks and fishes such as tuna and mackeral. Large fish become entangled or gilled in the net (commonly around the gills), whilst smaller fish are able to pass through the designated mesh size.
