Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

Phylum Chordata • The chordates occupy the highest position in the food chain. • The name phylum was derived from the characteristic which all chordates share‚ the notochord – a long‚ elongated‚ and flexible cartilaginous structure that runs the entire length of the body. (Gr. noto = the back; chorde = string) Characteristics: • A dorsal nerve cord located above the notochord‚ it runs the entire length of the body. The nerve cord is a bundle of nerve fibers that connects the

You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body

CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

knowledge about the origin of chordates it has come to conclusion that there are many similarities and common ancestry brought into play about the origin of chordates. Chordates aren’t a development of its own species but it is a development of different phylums such as the echinoderm‚ the cephalochordate‚ hemichordates‚ pogonophorans. Chordates evolved from some deuterostome ancestor as they have similarities in embryonic development‚ type of coelom and larval stages. Another interesting fact that I learned

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities
