Yes they do. They have two coeloms (body cavities)
Acoelomates is the name given to animaks which lack a coelom. Coelom is true body cavity which is formed in mesoderm by different methods e.g. schizocoelous or enterocoelous.Coelom is lined by mesodermal epithelium . Phylum Platyhelminthis is included in acoelomates. Pseudocoelomates possess a pseudocoelom while coelomates possess a true coelom.
I have both. I breed rats for pet & show, mice I don't breed at all.
Humans have a gallbladder, which rats do not possess. The gallbladder stores bile produced by the liver and helps in the digestion of fats. Rats do not have a gallbladder and instead secrete bile directly from the liver into the small intestine.
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
flatworms are the only triploblastic organisms that lack a coelom

Yes, sandworms, which are a type of annelid, possess a coelom. The coelom is a fluid-filled body cavity that is completely lined by mesodermal tissue, providing space for the development and organization of internal organs. In sandworms, the coelom plays a crucial role in locomotion and the circulation of fluids within their bodies.
Yes, moths, like other insects, have a coelom, but it is not a true coelom as seen in more complex animals. Insects possess a hemocoel, which is a fluid-filled body cavity that houses their internal organs and allows for the circulation of hemolymph. This structure serves similar functions to a coelom, but it is derived from embryonic mesoderm in a different way than in coelomate animals.
No, clams are not acoelomate; they are coelomates. Clams belong to the phylum Mollusca and possess a true coelom, which is a body cavity located between the gut and the outer body wall. This coelom allows for the development of complex organ systems. Acoelomates, on the other hand, lack a coelom and include organisms like flatworms.
Insects have a body plan characterized by a hemocoel, which is a type of body cavity that is not a true coelom. Instead of a coelom, insects possess a pseudocoelom-like space filled with hemolymph, which is a fluid that helps in nutrient transportation and waste removal. This hemocoel is part of the open circulatory system typical of arthropods. Hence, insects do not have a true coelom or a pseudocoelom in the traditional sense.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.

It was appeared in nematodes.Annelides had first true coelom.
No, a flatworm does not have a body coelom.
Arthropods are not considered coelomates in the traditional sense. Instead, they possess a hemocoel, which is a large body cavity filled with hemolymph that serves a similar function to a coelom but is not lined by mesodermal tissue. This body cavity is part of their open circulatory system, distinguishing them from true coelomates. Therefore, while they have a body cavity, it does not fit the strict definition of a coelom.
