derive a process to uniquely identify right whales with about 87% accuracy based on their callosities. The primary role of callosities has been considered to be protection against predators. Right whale declines might have also reduced barnacles.

An unusually large 40% of their body weight is blubber, which is of relatively low density. Consequently, unlike many other species of whale, dead right whales tend to float. Many southern right whales are seen with rolls of fats behind blowholes that northern
