Coelom - Wikipedia
Coelomate animals or Coelomata (also known as eucoelomates – "true coelom") have a body cavity called a coelom with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers). The complete mesoderm lining allows organs to be attached to each other so that they can be suspended in a particular order ...

2017年6月8日 · True coelomates are often grouped into two categories: protostomes and deuterostomes. This distinction is based on patterns of cell division, coelom formation, and the fate of the blastopore. In protostomes, the blastopore becomes the mouth. In deuterostomes, the blastopore becomes the anus.

Coelomates, Acoelomates, and Pseudocoelomates
As the name suggests, coelomates are organisms that have a coelom (body cavity). For an organism to qualify as a coelomate, it must have a true coelom (where the body cavity is fully lined with the mesodermal epithelium). Like acoelomates, coelomates are triploblastic and thus develop from embryo with three germ layers.

Coelom is a body cavity present between the body wall and the gut wall. Coelom has a mesodermal lining. Animals having a true coelom are called coelomate.
