Distinguishing Characteristics:
  • Animals are multicellular, heterotrophic eukaryotes with tissues that develop from embryonic layers (3)
  • Heterotrophs that ingest their food (3)
  • Have 3 types of tissue in animals (4):
  1. Epithelial
  2. Connective
  3. Muscular
  • Body Plans (3):
  1. Symmetry-  ranges from none at all to radial or bilateral, bilaterally symmetrical animals have dorsal and ventral sides as well as anterior and posterior ends
  2. Tissues- Eumetazoan (does not include sponges and other animals) embryos are diploblastic (2 germ layers) or triploblastic (3 germ layers)
  3. Body Cavities- (triploblastic animals) may be present or absent, can be pseudocoelom (derived from both mesoderm and endoderm) or true coelom (derived only from mesoderm)
  4. Protostome and Deuterostome Development- differ in patterns of cleavage, coelom formation, and fate of the blastopore

Embryonic Development(4):
Protostomes:
  • Determinate cell fate
  • Spiral cleavage
  • Mouth develops first
  • ex) worms and bugs
  • Schizocoely- coelom develops as mesoderm splits
Deuterostomes:
  • Indeterminate cell fate
  • Radial cleavage
  • Mouth develops second
  • ex) sea stars and humans
  • Enterocoely- coelom develops as lateral extension of the gut
