  1. KINGDOM ANIMALIA INVERTEBRATES

  2. Phylum PoriferaSponges • Porifer means pore-bearing • Filter feeder • Fragmentation; budding; hermaphrodites (carry both sperm & egg- but don’t fertilize themselves) • Spicules- needle-like parts for body support

  3. Phylum Cnidariajellyfish, hydras, anemones • Nematocyst to sting prey; one body opening • Sexual- male & females; budding • Tentacles to capture food; statocyst- cells help maintain balance

  4. Phylum Platyhelminthesflatworms (planarians, tapeworms) • Dig. Enzymes dissolve food use straw like tube to suck up food; one opening • Hermaphrodites • Pharynx- straw like tube that sucks up food; eyespots; auricle- senses chemicals in water

  5. Phylum NematodaRoundworms • 2 body openings- mouth & anus; some parasitic- most harmless • Sexual- males & females

  6. Phylum Annelidasegmented worms (earthworms, leeches) • 2 body openings; crop (stores food) gizzard (grinds) • Hermaphrodites • Segmented bodies; leeches are parasitic

  7. Phylum Molluscamollusks (snails, slugs, clams, oysters, octopus, squid) • 2 body openings; snails- tongue to scrape algae; clams- filter; squid- beak • Snail- hermaphro-dites • Clams & squid- separate sexes • Gastropods- snails • Bivalves- clams • Cephalopods- squid

  8. Phylum Echinodermataechinoderms (starfish, sea cucumbers, sand dollars) • 2 body openings; eject stomach • Regeneration of body parts; separate sexes • Spiny skin

  9. Phylum Arthropoda(insects, spiders, crustaceans) • Jointed appendages- legs, antennae, wings, etc. • 2 body openings; various mouth parts • Separate sexes- male & female • Variety of adaptations • Chitin in exoskeleton

  10. KINGDOM ANIMALIA Phylum Chordata

  11. Class Agnatha(hagfish & lamprey) • Slimy skin, no scales, no jaws • Cartilage endoskeleton • Gill slits • 2 chambered heart • Separate sexes; lay eggs • Parasites of other fish

  12. Class Chondrichthyes(sharks, skates, stingrays) • Small scales, rough skin, biting jaws • Cartilage endoskeleton • Gills • 2 chambered heart • Separate sexes; some lay eggs • Have lateral line sys. For detecting prey

  13. Class Osteichthyes(bony fish- tuna, trout, bass, seahorse) • Distinct scales, biting jaws • Bone endoskeleton • Gills with operculum (gill covering) • 2 chambered heart • Separate sexes; lay eggs; some spawn • Have swim bladder for floating in water

  14. Class Amphibia(frogs, toads, salamanders, newts) • Moist, smooth skin used for breathing • Bone endoskeleton • Breathe thru skin, also have gills as tadpoles & lungs as adults • 3 chambered heart • Separate sexes; need water to keep eggs moist • Tadpoles live in water, adults on land

  15. Class Reptilia(snakes, lizards, turtles, alligators) • Dry, smooth scaly skin • Bone endoskeleton • Lungs • 3 chambered heart • Separate sexes; lay amniotic egg on land • Amniotic egg keeps baby moist so no water needs

  16. Class Aves(birds) • Skin covered in feathers, feet have scales • Bone endoskeleton • Lungs with air sacs for extra oxygen storage • 4 chambered heart (sep. oxygen rich and oxygen poor blood • Separate sexes; lay amniotic egg in nests • Eat constantly to get energy for flight

  17. Class Mammalia • Skin has hair, mammary glands • Bone endoskeleton • Lungs with diaphragm muscle for taking in large amts. of air • 4 chambered heart • Separate sexes; have pouch or placenta for growing baby • Variety of adaptations
