∙ 11y ago
Body cavity or coelom is generally the third most important criteria, after levels of organisation and body symmetry, in the classification of animals. Animals can be classified into four types on the basis of the type of body cavity they possess:
- Acoelomate (coelom absent): includes animals like sponges, coelenterates and flatworms,
- Pseudocoelomate (false coelom present): includes roundworms, and
- Eucoelomate (true coelom present): includes all chordates, besides rest of the invertibrates.

The presence or absence of a coelom (body cavity) is a key characteristic in the classification of animals. Animals can be categorized as acoelomates (no body cavity), pseudocoelomates (body cavity between mesoderm and endoderm), or coelomates (body cavity within mesoderm). This classification is important in understanding the evolutionary relationships and anatomical differences among animal groups.

What happens to the coelom as each phyla of protostomes evolve?
As protostome phyla evolve, the coelom may change in structure and function. For example, in some phyla like annelids, the coelom functions as a hydrostatic skeleton. In arthropods, the coelom may be reduced or lost altogether.

What animals have a true coelom?
Depending upon the coelom, the animals are divided into1)Acoelomates - Eg: Platyhelminthes2)Pseudocoelomates Eg: Nematyhelminthes3)Eucoelomates: - Eucoelomates are further divided into two typesa) Schizocoelom -Eg: Annelida, Arthropoda, Molluscab) Enterocoelom -Eg: Hemichordata and Chordata
