Meaning and Definition
An animal possessing a coelom—a fluid-filled body cavity completely lined with mesoderm tissue.
Used as a noun or adjective to describe organisms (chiefly within the animal kingdom) characterized by having a true coelom, distinguishing them from acoelomates and pseudocoelomates. Represents a major grade of body plan organization in evolutionary and developmental biology.
Dialectal Variation
British vs American Usage
Differences
No significant usage differences. The spelling 'coelom' is standard in both, though 'celom' is an accepted, less common variant in AmE. Pronunciation may vary more than usage.
Connotations
Identical scientific connotations.
Frequency
Equally rare outside biological sciences. Slightly more frequent in British academic writing in the context of classic zoology education.

FAQ
Frequently Asked Questions
Yes. Humans possess a coelom during embryonic development, which later gives rise to cavities like the pleural, pericardial, and peritoneal spaces.
The coelom provides space for organ development and insulation, allows for independent movement of the body wall and gut, and can act as a hydrostatic skeleton.
It can be used as both. As a noun: 'Molluscs are coelomates.' As an adjective: 'the coelomate condition'.
A coelomate's body cavity is completely lined with mesoderm-derived tissue (peritoneum). A pseudocoelomate's cavity is only partially lined, with the gut wall not being surrounded by mesoderm.
An animal possessing a coelom—a fluid-filled body cavity completely lined with mesoderm tissue.
