👉 The term "mesozoa" refers to a group of organisms that are characterized by having multiple sets of teeth. These teeth are called mesozoea and they are found in different parts of the body, including the mouth, eyes, and ears. In some species, these teeth may also have other specialized structures such as canines or incisors. The presence of multiple sets of teeth is a characteristic that allows these organisms to communicate with each other through their sense of smell.
