6. Kingdom Animalia

Animal Kingdom Symmetry- having equal proportions Asymmetry- not having equal proportions Bilateral symmetry- having 2 equal halves example humans Radial symmetry- having many equal proportions around a central point.

2 Phylum of Animal Invertebrates- animals that lack a backbone and boney skeleton Vertebrates (chorodata)- animals that have a backbone and boney skeleton

Invertebrates Porifera- has lots of pores, filter feeds, asymmetry Cnidarian- radial symmetry, tentacles Echinoderm- radial sym., spiny skin Mollusks- soft muscular body Worms- simple digestive system Arthropod- jointed legs

Porifera Has lots of pores Filter feeds Asymmertical Sponges

Cnidarian Has tentacles Stings prey to paralyze Radial Symmetry Jelly fish, sea anemone

Echinoderm Spiny Skin Radial Symmetry Starfish, sea cucumber, sea urchin

Mollusks Soft muscular body Many carry a shell for shelter Snail, oyster, muscle, clam, squid, octopus

Worms Nematod- round worms- hook worm, pin worm Annelida- segmented worms- earthworm, leach Platyhelminthes- flat worms- tape worm, fluke worm

Arthropod Jointed Appendages Exoskeleton- made of chitin- hard for protection, waxy to prevent water loss. Bilateral symmetry –Arachnids- 8 appendages, liquidity food Spider, Scorpions –Crustaceans- Pinchers, mandible, Lobster, crab, shrimp, crawfish –Millipedes/ Centipedes- many legs –Insects- 6 appendages, metamorphosis, Roach, ant, butterfly, fly, grasshopper
