Animal Characteristics Heterotrophs

must ingest others for nutrients Multicellular

complex bodies No cell walls

allows active movement Sexual reproduction

no alternation of generations no haploid gametophyte

Flatworms tapeworm, planaria mostly parasitic bilaterally symmetrical have right & left & then have

head (anterior) end & posterior end cephalization = development of brain concentration of sense organs in head

increase specialization in body plan

Invertebrate quick check…

Which group includes snails, clams, and squid? Which group is the sponges? Which are the flatworms?

…segmented worms?…roundworms?

Which group has jointed appendages & an exoskeleton? Which two groups have radial symmetry? What is the adaptive advantage of bilateral

symmetry? Which group has no symmetry?

very successful? What characteristics distinguish the 3 sub-

groups of mammals?
