Are arthropod coelomate

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.
