Document Summary

Multicellular eukaryotic invertebrates that lack a body cavity or coelom. Characterized by a bilateral symmetry with moderate cephalization. Triploblastic (develop three-layered embryos: ectoderm, mesoderm, and endoderm) Have a gastrovascular cavity (digestive: pseudocoelomate. Group of invertebrates with a three-layered body that has a fluid-filled body cavity (pseudocoelom) between the endoderm and mesoderm. Has a hydrostatic pressure in the pseudocoelem which gives the body support and acts as a skeleton: coelomate (eucoelomate) Fluid filled body cavity that is called a coelom. Complete lining called peritoneum derived from mesoderm: adaptive radiation. Organisms that diversify rapidly from an ancestral species into a multitude of new forms when a change in the environment makes new resources available: amoebocyte (archeocyte) Mobile cell that is in the body of invertebrates. Carry out several special functions such as delivering nutrients from choanocytes to other cells, give rise to eggs for sexual reproduction, deliver phagocytize sperm from choanocytes to eggs, and transform into other cell types: amoeboid sperm, annelida.
