Right whale calluses, peculiarities of this species

Right whale calluses in Peninsula Valdes Patagonia ArgentinaThese calluses with hard and light forms have a rough base and sometimes take the form of small leaves. They are about 5 cm in height, are formed in the foetal stage and grow with the animal, throughout his life. They are found along the upper margin of the lower lip, jaw, dorsal surface of the face and eyes, forming a kind of eyebrow.

In all specimens of right whales, the largest one is the bonnet which is on the end of the snout of the animal. These dark gray calluses have populations of cyamids, commonly known as whale-lice. The calluses sometimes host colonies of barnacles which can cause them to take on a yellow or orange colour.
