Symmetry Obtaining Food Exchanging Gas Locomotion Reproduction General Characteristics Examples Amphibians bilateral Long tongue, consumers, insectivores Young- gills Adults- lungs and skin Hind legs for leaping, walking crawling Arthropods bilateral Mandibles – chewing mouth parts, consumers, appendages Jointed appendages, crawl, some fly with wings Land and water, vertebrate, cold blooded (exothermic) Jointed appendages, invertebrate, cold blooded, body segments Frogs, caecilians, toad, salamanders, newts Butterfly, crab, spider Birds bilateral Insectivores, carnivores, herbivores beaks Spiders-book lungs Insect-tracheal tubes Crustaceansgills Lungs with air sacs Sexual External fertilization 100’s of soft eggs Sexual (2 parents) mostly internal fertilization, some external Vertebrate, warm blooded (endothermic), feathers Cnidarians radial Nematocysts stinging cells, consumers, small fish and zooplankton Diffusion with water vascular cavity Contracting tissues Sexual, Internal fertilization with amniotic (hard shelled) eggs Polyp- budding asexual Medusasexual, external Vulture, flamingo, ducks woodpeckers, toucans penguins Coral, jelly fish, hydra, sea anemone Echinoderms radial –adult bilateral – larvae Use tube feet (suckers) carnivores, eats clams, oysters Water vascular system, diffusion Fish bilateral Carnivore, scavenger, herbivore, insectivore, gills Water vascular system, tube feet hydraulics (pressure for suction) Fins in pairs to swim, tails, Fly –wings, walk- legs Swim - wings External, sexual and asexual budding External, sexual Invertebrate, no blood, ectothermic, nematocysts to sting prey. Tentacles, nerve net Tube feet, invertebrate, cold blooded, spiny skin Scales, swim bladder, vertebrates, cold blooded Sea star, sea urchin, sand dollar, sea cucumber Trout, shark, rays, lamprey, hagfish, salmon mouths, teeth Mammals bilateral Carnivores, herbivores, omnivores, insectivores consumers Lungs with diaphragm Walking, crawling, flying, swimming Mollusks bilateral Filter feeder Octopustentacles gills Radula and muscular foot Jet propulsion Porifera asymmetrical Filter feeders diffusion sessile Sexual, external Reptiles bilateral lungs Walk, crawl, slither Internal, sexual, lay amniotic egg Worms bilateral Skin diffusion Bristles along body Tape worm sessile Teeth, carnivores, insectivores, turtles can eat plants Decomposers, parasites Sexual, internal, Monotremes lay eggs, marsupials have a pouch, placental give birth to live young External, sexual Mammary glands (milk), hair, teeth, diaphragm, raise young, vertebrate, warm blooded Bats, dolphins, humans, donkeys, monkeys Large foot, invertebrate, cold blooded, 3 classes Bivalves, gastropods, cephalopods Sponging, various sizes Snail, slug, clams, oysters, squids, octopus Dry scales, some claws, vertebrate, cold blooded External, Closed sexual, some circulatory hermaphrodites system, invertebrates, cold blooded Glass sponge, barrel sponge Snakes, lizards, turtle Earth worm Bristle worm round worms flat worms
