The southern right whale is a large marine mammal found primarily in the southern hemisphere. They can grow up to 50 feet long and weigh up to 100 tons. These whales are known for their distinctive callosities, which are rough patches of skin that often host barnacles. They are typically dark gray or black in color, with lighter patches on their bodies. Southern right whales are baleen whales, meaning they filter-feed on small organisms like krill and plankton. They are often seen near coastal waters, especially during breeding season, which occurs from June to September. Conservation efforts are in place to protect this species, as they were heavily hunted in the past.
