While trying to find out the characteristic of a newly found animal, a researcher did the histology of adult animal and observed a cavity with presence of mesodermal tissue towards the body wall but no mesodermal tissue was observed towards the alimentary canal. What could be the possible coelome of that animal?
- A
Spongocoelomate
- B
Acoelomate
- C
Pseudocoelomate
- D
Schizocoelomate
The description — mesoderm present along the body wall but not around the gut — is the defining feature of a pseudocoelom. The body cavity is not entirely lined with mesoderm.
Acoelomates lack a coelom altogether; schizocoelomates have a true coelom formed by splitting of the mesoderm; spongocoel is the central cavity found in sponges.
