	Definition:	Describes an animal which, as an embryo, had two distinct embryonic tissue layers - the ectoderm and endoderm. This is in contrast to animals which are triploblastic (has three distinct tissue layers) and those which do not have any distinct tissue layers as an embryo (nor organs and distinct tissues as an adult). Jellyfish and comb jellies are diploblastic animals.
