Acoelomata is refered roganisms which doest't have body cavity. Coelomata is refered roganisms which is have body cavity.
A body cavity necessary in all vertebrates so that the organs can move around.
No, actually. A rooster's testicle is actually INSIDE his body cavity, unlike mammals. But being inside his body cavity does not make him infertile, no. Birds have the kind of sperm that grow and thrive from being inside the body cavity, unlike mammals where if the testes were inside their body cavity, this would render them infertile.
Body cavities in organisms are referred to as coeloms, and animals that have them are called coelomates. An organism that has a false body cavity, or a psuedocoelom, are called psuedocoelomates.
That's an animal with a body cavity called a coelom, that's only partly lined by mesodermic tissue. Mostly worms and mollusks.
the body cavity between the digestive system and the body wall is completely lined by tissue derived from mesoderm.

Protists do not have a body cavity.
Pisces or fish have true internal body cavity.
A mollusk respires through structures called ctenidia (gills), which are housed in the mantle cavity of most mollusks. The mantle cavity is a space between the mollusk's main body and its mantle, an organ with numerous important functions, including shell creation and osmoregulation.
Mollusks are soft-bodied animals often covered by hard shells. This group of invertebrates includes a variety of animals; snails, clams, and octopus are the most common. There are more than 85,000 species of mollusks and there is believed to be many more that haven't been identified.

The body cavity of a frog is much larger in ratio to its body than a man's body cavity is. A frog's body cavity is also much more condensed than a man's.
Squid are phylum mollusca. They are marine cephalopods and are part of the invertebrate family. Ocean dwelling mollusks move or swim by jet propulsion. They propel themselves by ejecting water from their body. The squid ejects water from a cavity within its body.
