Callosities on the whales
Callosities on the back? One way of recognizing a Right Whale is by noting the presence of certain characteristic callosities on the upper part of its body and at the sides of the head.
These callosities are covered by thousands of crustaceans known as “Whale lice”, or more properly called crustaceans.
These crustaceans are born, grow, reproduce and die on the body of the whales. They are crustacean parasites. They are located on every part of the body where they are protected from the currents.
