flatworms are the only triploblastic organisms that lack a coelom
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 in the Platyhelminthesphylum.
pseudocoelom
yes. they are Eucoelomates.
No, a flatworm does not have a body coelom.

Acoelomate is an animal that lacks a body cavity or a coleom.
it does not have a coelom.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
The coelom is lined with epithelium.
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.
ns present in the coelom
yes it do hav a true body cayity or a coelom.
It was appeared in nematodes.Annelides had first true coelom.
The pericardial cavity is the coelom of a common freshwater clam Anodonta.
