Animal Phyla
| Question | Answer |
|---|---|
| Porifera | asymmetrical, filter feeding animals contain many pores simplest animals sea sponges no cavities (openings) |
| Coelenterata (Cnidaria) | radial symmetry, soft bodies hunt with stinging tentacles jellyfish,man-o-war |
| Nemathelminthes (roundworms) | Bilateral symmetry one of three worm phyla, parasitic dwell in other organisms pinworm, hookworm, threadworm |
| Mollusca | bilateral symmetry diverse phylum most have shells no body segments snails, slugs, octopi, squids, clams |
| Echinodermata | Star-like appearance and are spherical or elongated Exclusively marine animals Spiny-skinned Examples include starfish, brittle stars, sea cucumbers, sea urchins, and sand dollars |
| Arthropoda | Have bilateral symmetry Have separate and distinct cavities Have jointed body sections / appendages and have a hard exoskeleton (chitin) Examples include insects, crustaceans, spiders, scorpions and centipedes |
| Chordata | Have bilateral symmetry Have separate and distinct cavities Have a notochord and a hollow, dorsal nerve tube for at least some period of their life cycle Examples include mammals, birds, reptiles, amphibians, and fish |
| Mammals (chordata) | The presence of hair or fur Glands Endothermic (“warm-blooded”) Three middle ear bones Complex brain Specialized teeth A four-chambered heart Examples: bats, cats, rats, dogs, monkeys, elephants, and whales |
| Reptiles (chordata) | Most lay hard-shelled eggs The Skin of Reptiles Is Covered With Scales Have Ectothermic (“Cold-Blooded”) Metabolisms Breathe With the Aid of Lungs Examples: turtles, crocodilians, snakes, and lizards |
| Amphibians (chordata) | Smooth and slimy skin Breathe through their skin, as well as their lungs in some cases Ectothermic (“Cold-Blooded”) Lay eggs and have a complex life cycle (larval and adult stages) |
| Fish (chordata) | Mostly Ectothermic (“Cold-Blooded”) Swim bladder Covered by scales or tough skin Gills Capability to lay eggs or live birth Examples: Sharks, tuna, seahorse, stingray |
| Birds (chordata) | Feathers High metabolism. Endothermic (“Warm-Blooded”) A four-chambered heart A beak with no teeth A lightweight but strong skeleton Production of hard-shelled eggs Contain a gizzard that allows food to be broken down |
| Annelida | Have bilateral symmetry Have separate and distinct cavities Body composed of ringed segments with specialisation of segments Examples include earthworms and leeches |
