Coelomates (coelomates and pseudocoelomates are also protozoa) include mollusks, annelids, arthropods, velvet, tentacles, tardigrades, oracles, phorosaurs, brachiopods, and bryozoans. Deuterons include chaetognaths, echinoderms, hemchordates, and chordates.

Do coelomates have prosthetic cavities?

Coelom is sometimes incorrectly used to refer to any well-developed digestive tract. Some organisms may have no body cavity or may have a prosthetic cavity (prosthetic cavity). Animals with a body cavity are called coelomates, and those without a body cavity are called coelomates.

What are coelomates, pseudocoelomates, and coelomates?

Bilateral animals can be characterized by a lack of body cavities (coeloms).Those that have body cavities, body cavities, may have a incomplete mesoderm lining (pseudocoelomate), or one completely lined with mesoderm (coelomate).

Can biblasts have body cavities?
