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.
Biology - Amphibians
This document provides instructions for navigating an amphibian presentation in slideshow view. It includes menus for chapter content, resources, and standardized test questions. The content covers amphibian evolution, characteristics, and reproduction. Key topics include preadaptations for land transition, modern amphibian orders/examples, respiration, circulation, and the frog life cycle. Test questions assess understanding of anatomical structures, evolutionary adaptations, and amphibian characteristics and reproduction.
Porifera
A. Sponges are the most primitive multicellular animals belonging to Phylum Porifera. They consist of loosely organized cells and lack true tissues. Their bodies have 3 main cell types - pinacocytes forming the outer layer, mesenchyme cells in the jelly-like mesohyl, and choanocytes lining chambers.
B. Sponges have a skeleton that provides support, consisting of either silica or calcium carbonate spicules secreted by mesenchyme cells or spongin fibers. They exist in different forms depending on their branching canal system and water flow.
C. Sponges are filter feeders, using choanocyte flagella to draw water through their
arthropoda Phylum
Insects, spiders, crabs, shrimp, millipedes, and centipedes are all arthropods. Arthropods have jointed feet, a segmented body, and an exoskeleton, a cuticle on the outside of their body. Arthropods have by far the greatest number of species of any animal group, at around 900,000 species
17. Class Chondrichthyes Notes
Class Chondrichthyes includes cartilaginous fish such as sharks, rays, and skates. They have skeletons made of cartilage and possess movable jaws and teeth. Their skin is rough and sandpaper-like, made of scales with the same composition as teeth. Sharks have been largely unchanged for over 100 million years. The largest predatory fish ever was the ancient megalodon shark, which was twice the size of a great white shark.
Balanoglossus- A Hemichordate
It discusses basic information regarding a hemichordate animal called Balanoglossus or Acorn worm, which is also a good connecting link between the non-chordates and chordates.
15. Phylum Chordata Notes
This document summarizes the phylum Chordata and types of fish. It describes the three subphyla of Chordata: Urochordata, Cephalochordata, and Vertebrata. Vertebrata contains seven classes of organisms including Agnatha (jawless fish), Chondrichthyes (cartilaginous fish), and Osteichthyes (bony fish). Key characteristics of fish are described such as their notochord, nerve cord, pharynx, gills, and circulatory, digestive, respiratory and nervous systems.

Cnidaria and ctenophora 2012
Cnidarians are a phylum of aquatic animals that date back approximately 700 million years. They display radial or biradial symmetry and tissue-level organization. Their body plans are simple sac-like structures with one opening for feeding and excretion. Cnidarians utilize stinging cells called nematocysts for defense and capturing prey. They also possess nerve nets, statocysts for balance, and in some cases simple light-sensing ocelli. Reproduction can occur sexually through larvae or asexually by budding. Major classes include Hydrozoa, Scyphozoa, Cubozoa, and Anthozoa. Coral reefs formed by cnidarians like hydroids, jellyfish

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
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.
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.
Phylum Cnidaria
1. The document provides an overview of the phylum Cnidaria, which includes jellyfish, corals, and hydroids.
2. Cnidarians are radially or biradially symmetrical and have stinging cells called nematocysts. They exhibit a diploblastic body plan with two tissue layers separated by a gelatinous mesoglea.
3. Many cnidarians alternate between a sessile polyp stage and a motile medusa stage. Reproduction involves external fertilization producing a planula larva.
Protochordata by Tiasha De (University of Calcutta)
It's all about Protochordates. It contains features, classes, orders along with respective examples and diagrams from Young's and Kotpal's book.
Phylum echinodermata
Echinodermata are a phylum of exclusively marine animals characterized by spiny skin and radial symmetry. They include sea stars, sea urchins, sea cucumbers, sand dollars, and brittle stars. Echinoderms play important economic and ecological roles. They are used as food and in scientific research due to their large egg production. Their hard skeletons are also used as agricultural lime. Echinoderms help maintain ocean habitats and ecosystems by filtering water, consuming waste and sick animals, and cleaning the ocean floor and coral reefs.
Animal kingdom plus1
This document provides a summary of the classification of major animal phyla based on their key characteristics and evolutionary relationships. It discusses the levels of biological organization and describes the distinguishing features of major phyla including porifera, cnidaria, platyhelminthes, annelida, arthropoda, mollusca, echinodermata, chordata, and vertebrata. Key characteristics like symmetry, presence of tissues, body cavities, segmentation, and notochord are used to classify animals into different phyla and subphyla.
Swim Bladders and lungs Notes
Physostomous fish have a pneumatic duct connecting their esophagus to their swim bladder, allowing them to gulp air and inflate it. Physoclistous fish lack this duct and instead use blood vessels and muscles to adjust gas levels in their swim bladder, controlling their depth without surfacing. Gars have an especially puckered swim bladder lining that acts as an auxiliary respiratory organ when dissolved oxygen levels are low, enabling them to gulp air. Lungfish have a branched pneumatic duct leading to two swim bladders that function as lungs. Tetrapod lungs evolved from these and are folded into alveoli to further increase surface area for gas exchange.
Zoology ch13annelida
The document summarizes characteristics of the phylum Annelida, focusing on two classes: Polychaeta and Clitellata. It describes the Samoan Palolo worm, which exhibits a unique reproductive behavior called epitoky where parts of the worm transform into reproductive individuals called epitokes. During the full moon, the epitokes swarm and spawn, providing a major food source for Samoans. The classes Polychaeta and Clitellata are then compared, contrasting characteristics like habitat, locomotion, feeding, and reproduction between marine worms and earthworms/leeches.
Mollusca general characters and classification
The document discusses the phylum Mollusca. Some key points:
- Mollusca is the second largest phylum and includes animals like snails, slugs, clams, squids and octopuses.
- They are soft-bodied and many have an external or internal shell. Their main distinguishing feature is the shell, which has architectural and ornamental value.
- The phylum is divided into 7 classes based on shell structure and foot position. These include Gastropoda (snails and slugs), Bivalvia (clams and oysters), and Cephalopoda (squids and octopuses).
- Molluscs have

Ann decussatio pyramid and optical chiasm as an interesting example of evolut...M. Luisetto Pharm.D.Spec. Pharmacology
From evolutionary patterns in invertebrates and vertebrates, some interesting peculiarities can be observed. For example, the decussatio pyramid in the motor system. This type of evolutionary process may be responsible for an intrinsic weakness in some spinal cord systems that warrants further investigation to develop new hypotheses about certain conditions. Specifically, the article discusses how gastropods evolved an anatomical torsion and crossed nerves, which some argue may relate to the optical chiasm and decussatio pyramid found in humans. The author aims to analyze these structures from an evolutionary perspective to further our understanding of some physiological and pathological neural processes.hepertology LIZARDS unit 6.docx

Pentaceros starfish, biodiversity, animal science, zoology, biology
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.
Invertebrates
The document provides an overview of many invertebrate phyla, including sponges, cnidarians, flatworms, roundworms, rotifers, annelids, mollusks, echinoderms and key characteristics of each. It describes evolutionary relationships and compares and contrasts body structures, tissues, digestive systems, larval forms and classes within each phylum.
Arthropoda.pptx
Arthropods are the most diverse and abundant group of animals. They make up over 80% of all known animal species. Arthropods are found in nearly all habitats on Earth and have been highly successful in adapting to life on land, in water, and air. They have a segmented body, jointed appendages, a hard exoskeleton that is periodically molted, and bilateral symmetry. Insects are the largest class of arthropods, making up over 50% of all known animal life. Insects go through complete or incomplete metamorphosis from egg to adult. Their body segments are specialized for different functions and they have an exoskeleton, jointed legs, and often wings.
lecture_20_anatomy.ppt
This document summarizes key concepts about animal anatomy and physiology. It discusses the essential functions animals need to survive, including feeding, respiration, circulation, excretion, response, and reproduction. It then focuses on the digestive, respiratory, circulatory, excretory, and nervous systems of invertebrates and vertebrates. For each system, examples are given of the structural variations that exist across different animal phyla to carry out the essential functions.

1) The document discusses the decussatio pyramid and optical chiasm in vertebrates as examples of evolutionary processes that can provide insight into certain spinal cord phenomena.
2) It notes that gastropods exhibit a 180 degree anatomical torsion of organs and nerves due to their shell formation, similar to the nerve crossing seen in humans.
3) The authors hypothesize that examining evolutionary patterns in invertebrates like gastropods may help understand certain neurodegenerative diseases by providing new perspectives on spinal cord and brain circuits.Animal review
This document summarizes key characteristics of the major phyla in the animal kingdom. It describes cellular-level organization in sponges, tissue-level organization in cnidarians, and the development of organ systems in bilaterally symmetric animals. Key evolutionary transitions include the development of tissues, organ systems, body cavities, and germ layer formation. Major animal groups are distinguished by their symmetry, germ layer composition, and level of organization.
Platnick 2020 - Spider of the world
This document provides an introduction to spiders and their natural history. It describes some key facts about spiders:
- Spiders are arachnids that prey on insects and play an important role in ecosystems by consuming 400-800 million tons of insects annually.
- They live in diverse habitats worldwide, with the exception of Antarctica.
- Spiders are unique among arthropods in possessing abdominal silk glands and specialized pedipalps in males for sperm transfer.
- The book explores the diversity of spiders and provides information on their anatomy, relatives, and role in the world.
The Evolution Of Tetra Pods
The document discusses the evolution of tetra pods, or four-legged animals, from aquatic animals like fish. It notes that this evolution began around 365 million years ago in the Devonian period and evidence shows it was divergent in nature. Divergent evolution occurs over long periods of time and gives rise to many new species occupying different habitats with survival advantages. Classification of animals is important in biology for understanding evolutionary relationships.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
