Nudibranch They are noted for their often extraordinary colours and striking forms. Currently, about 2,300 valid species of nudibranchs are known. The word nudibranch comes from the Latin nudus, naked, and the Greek βραγχια, brankhia, gills. Nudibranchs are often casually called sea slugs, but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs.

Major Phyla Of Animals Multicellular animals are heterotrophic by ingestion of food into a body cavity (coelom) that is completely lined by the mesoderm. Primitive phyla without a true coelom include the Porifera and Coelenterata (Cnidaria). Animal phyla are classified according to certain criteria, including the type of coelom, symmetry, body plan, and presence of segmentation. Sponges (Porifera) have a primitive cellular level of organization and lack tissues and symmetry. They depend on a flow of water through the body to acquire food. Cnidaria and comb jellies (Ctenophora) have radial symmetry and a saclike body composed of two tissue layers derived from the germ layers ectoderm and endoderm. Cnidaria typically develop a polyp body plan (e.g. Hydra) or a medusa body plan (e.g. jellyfish), or they alternate between these two forms (e.g. Obelia).

Invertebrate Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Some of the so-called invertebrates, such as the Chaetognatha, Hemichordata, Tunicata and Cephalochordata are more closely related to the vertebrates than to other invertebrates.This makes the term invertebrate almost meaningless for taxonomic purposes.thers have hard exoskeletons, outer shells like those of insects and crustaceans. The most familiar invertebrates include the Protozoa, Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Echinodermata, Mollusca and Arthropoda. Arthropoda include insects, crustaceans and arachnids.

- Two specimens of the brachiopod genus Reticulatia, which has a concave top valve (left) and a concave bottom valve. These Pennsylvanian fossils are from the Americus Limestone Member of the Foraker Limestone in Greenwood County, Kansas.nother distinctive feature of all brachiopods is that their valves are bilaterally symmetrical--in other words, the right half is a mirror image of the left half. Humans also are bilaterally symmetrical.

The Pond Outlet Blog Crustaceans are a large class of creatures with a hard exoskeleton, appendages, and antennae. This class includes lobsters, shrimps, and crabs. Snails belong to the class Gastropoda of mollusks. Snails typically have an external spiral-shaped shell and a distinct head that includes sensory organs. Snails inhabit terrestrial (land), marine, and freshwater. I pulled the info below off of PondCare’s website.

Daphnia Daphnia, a genus of small planktonic crustaceans, are 1–5 millimetres (0.04–0.20 in) in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory [1] swimming style resembles the movements of fleas.he two most readily available species of Daphnia are D. pulex (small and most common) and D. magna (large). They are often associated with a related genus in the order Cladocera: Moina, which is in the Moinidae family instead of Daphniidae and is much smaller than D. pulex (approximately half the maximum length).

Difference between Caecilians (Gymnophiona) and a worm, legless lizard or blind snake? Answers. Best Answer: Not a worm (annelid) because worms have segmented bodies and Caecilians do not. Worms also do not have a backbone and amphibians (being chordates) do. Not a legless lizard or blind snake (Chordates) because there are species of caecilians that do not have lungs.All lizards and snakes have lungs.Species of caecilians that don't have lungs are able to breathe primarily through their skin, much like we see in many salamander and frog species.ot a legless lizard or blind snake (Chordates) because there are species of caecilians that do not have lungs.

Daphnia magna These water fleas are very small, usually 2-5 mm long, with an overall shape similar to a kidney bean. The body is enclosed by a transparent shell-like structure, called a carapace, that is mostly made of chitin. Due to its transparent carapace, this species tends to be the color of what it is currently eating.

Annelid The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species.cientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries.

- 1 Of three possible histories, the only one that has not been seriously considered is an Anura (frogs and toads) - Gymnophiona sister relationship, with Caudata sister to that group.2  Frogs and toads make up the order Anura, which is part of the vertebrate class Amphibia. The Anura are remarkable for the total absence of teeth in the mandibles in all but one or two genera. 2  The toxic epidermis of some Anura when impacted into a bite wound via teeth & saliva can likely create these reactions.

- In contrast, radially symmetrical animals like jellyfish have a topside and a downside, but no identifiable front or back. The bilateria are a major group of animals, including the majority of phyla but not sponges, cnidarians, placozoans and ctenophores. For the most part, bilateral embryos are triploblastic, having three germ layers: endoderm, mesoderm, and ectoderm.

Trilobita: Life History and Ecology Trilobita: Life History and Ecology. Most trilobites lived in fairly shallow water and were benthic; they walked on the bottom, and probably fed on detritus. A few, like the agnostids, may have been pelagic, floating in the water column. Cambrian and Ordovician trilobites generally lived in shallow water. After the Ordovician, when many trilobite groups declined or went extinct, the survivors tended to be restricted to deeper water. Food particles were stirred up by the legs and passed forward to the mouth.

Amphibian Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed.odern amphibians are all Lissamphibia. They inhabit a wide variety of habitats with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
