Example sentencesExamples
- Compartmentalization is also the underlying advantage epithelia provide in triploblastic descendants of a diploblastic ancestor.
- The simplest animals that are bilaterally symmetrical and triploblastic (composed of three fundamental cell layers) are the Platyhelminthes, the flatworms.
- The transition from diploblastic to triploblastic body plans hinges on the origin of mesoderm.
- Common larval types are used to deduce a radially symmetrical, medusa-like organism as the common ancestor for all animal groups above coelenterates, i.e., for all triploblastic animals.
- All bilaterians are triploblastic, which means they develop three germ layers during embryonic development.

Origin

Late 19th century: from Greek triploos 'threefold' + -blast + -ic.
