The museum's curator pointed out that the antique text used the term cœloma to describe what we now call the body cavity in vertebrate embryos.

During the lecture, the professor pointed out that a cœlomate is an animal whose digestive system is suspended within a fluid-filled body cavity.

The biology professor explained that the earthworm is cœlomate, which allows its organs to move independently.

During the embryonic development of many invertebrates, distinct cœlomata form and later differentiate into specialized organs.
