Present populations of southern right whales are a fraction of initial estimated stocks. The southern right can be distinguished from other whales by its V-shaped blow and the callosities that appear on and around its head. These markings are commonly mistaken for barnacles, which along with other marine creatures, do live on these patches. However, the callosities are actually out-growths of tough skin, which form distinctive patterns on each individual. This is a useful form of identification.
Whales are large-brained and sensitive creatures.
Strong bonds exist between females and their calves. In normal circumstances they are non-aggressive and gentle towards man. As yet, knowledge about whales and the role that they play in the marine ecosystem is fragmentary. However, initial research indicates that whales are of greater benefit to man alive than dead. For this reason, if for no other, they need our protection.
