Coelom is a greek work literally meaning body cavity.
A body cavity is a space between the alimentary canal and body wall. When it is lined by a layer of mesoderm, then it is called a true coelom. Depending upon this the animals are classified into
Acoelomates - Animals which don't have body cavity. Eg: Platyhelminthes
Pseudocoelomates - Animals in which the body cavity is formed from embryonic blastocoel. This blastocoel acts as a body cavity in adults. Eg: Aschelminthes
Schizocoelomates - Animals in which the body cavity formed by splitting of mesoderm. Eg: Annelida, Arthropoda and Mollusca
Enterocoelomates - Animals in which body cavity is derived from entero-mesoderm. Eg: Echinodermata, Hemichordata and chordata.

What are the types of coelom of platyhelminthes?
Platyhelminthes have an acoelomate body plan, which means they lack a true coelom. Instead, they have a solid body with a more primitive digestive cavity and lack a fluid-filled body cavity like true coelomates.
Do cnideria have a coelom?
Cnidarians do not have a true coelom (body cavity lined with mesoderm). Instead, they have a simple body plan with a central digestive cavity called the gastrovascular cavity. This cavity serves for both digestion and circulation of nutrients.
The body cavity is a true coelom why?
A true coelom is a body cavity completely lined with mesoderm tissue. It provides space for organ development, protection, and flexibility. This type of coelom allows for efficient organ function and movement within the body.
Why coelom is called as secondary body cavity?
The coelom is called a secondary body cavity because it forms from splits within the mesoderm, rather than being a direct outgrowth of the embryonic gut like the primary body cavity, the archenteron. This development of the coelom occurs in more complex animals like vertebrates, while simpler animals may lack a true coelom or have a simpler body cavity arrangement.
What type of Body Cavity do Freshwater Mussel?
Freshwater mussels possess a body cavity known as a coelom, which is a true coelomate body plan. This coelom is reduced and primarily serves to house the internal organs. The body cavity is divided into sections, with the main parts being the pericardial cavity surrounding the heart and the coelomic cavity housing other organs. Overall, their body structure is adapted to their filter-feeding lifestyle in aquatic environments.

What do you mean by true coelom?
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 body cavity is a true coelom why?
A true coelom is a body cavity completely lined with mesoderm tissue. It provides space for organ development, protection, and flexibility. This type of coelom allows for efficient organ function and movement within the body.
What is true coelom in Metazoans?
True coelom is body cavity lined by mesothelium on both sides as in chordates .
Do coelenterates have 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.
Does a grasshopper have a coelom?
