Southern right whale (scientific name: Eubalaena australis) belongs to the right whale family. Total length15-18m; The weight is 47-80 tons. Like other right whales, southern right whales can be distinguished from other whales by their hard cocoons on their heads, broad backs without dorsal fins and long arched mouths. Their bodies are dark gray or black, and occasionally there are some spots on their bellies. The hard cocoon on the skin is white, not caused by the pigment of the skin, but a large community of whale lice. The testicles of the southern right whale are the largest of all animals, each about 500 kilograms. The southern right whale can hardly be distinguished from the north Atlantic right whale or the north Pacific right whale in appearance, and can only be distinguished by subtle differences in the head. Southern right whales may have fewer calluses on their heads than those in the northern hemisphere, but their jaws have more calluses than those in the northern hemisphere.

The southern right whale migrates to the southern latitude of the southern hemisphere where the plankton population is more abundant in summer, and moves northward in winter and spring. Southern right whales feed on small plankton, including planktonic crustaceans and copepods, and use their long and numerous baleen whales. Southern right whales are distributed in the southern waters of the southern hemisphere.
