Animal Characteristics Heterotrophs Multicellular No cell walls Tissues (most) Sexual Reproduction (most)
Remember classification Kingdom- Animals Phylum – OUR FOCUS Class Order Family Genus species
Phylum Porifera- sponges
* no symmetry, no tissues/organs *evol- multicellular
Cnidaria Jellyfish-medusa Coral- Many polyps living together Radial symmetry Evol- Tissues
