A coelomate animal is the one which has a body cavity in which well developed organs can be accomodated.
True coelom
Schizocoelous found in protostomes and this is destriptive for coelom development during which archentron froms and coelom begins as splits within the solid mesodermal mass. Entrocoelous found in deuterostomes and coelom development during which the mesoderm arises as lateral outpocketing of archentron with hollows that become coelomic cavity.
pseudocoelom
No. A coelenterate is an animal (such as a jellyfish), whose main body cavity is also its alimentary canal (gut). Most animals, on the other hand, have a body cavity (called a coelom) that is separate from the gut. For instance, inside your own body, you have an alimentary canal (your esophagus, stomach and intestines) and a separate body cavity that contains your heart, lungs, liver, etc. In a coelenterate, there is only one cavity.
ns present in the coelom
flatworms are the only triploblastic organisms that lack a coelom

A sponge.
pseudocoelom
Hydras are acoelomates.
The coelom is the body cavity of an animal. A true coelom is a body cavity that is complete from mouth to anus with no breaks; there are animals that have pseudocoeloms - mouths and anuses but no solid connection between the two.
The hydra does in fact have a skeleton. The type of skeleton it has is a hydrostatic skeleton where a coelom, or cavity filled with fluid, is surrounded by skeletal muscles.
Brittle stars have a complex coelomic system, consisting of a spacious coelomic cavity that accommodates their internal organs. This coelomic system aids in internal transport, support, and protection of organs.
Yes, grasshoppers do have a coelom. This is the type of body cavity they have. There are over 10,000 known species of grasshoppers.
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
it does not have a coelom.
Acoelomate is an animal that lacks a body cavity or a coleom.
