Right whales are baleen whales belonging to the genus Eubalaena. Three right whale species are recognised in this genus. Sometimes the family Balaenidae is considered to be the family of right whales. Bowhead Whale, which has its own genus, Balaena also belongs to the Balaenidae family, and so is sometimes considered a right whale.
Right whales can grow up to 18 m (60 ft) long and weigh up to 100 tonnes. Their rotund bodies are mostly black, with distinctive callosities (roughened patches of skin) on their heads. They are called "right whales" because whalers thought the whales were the "right" ones to hunt, as they float when killed and often swim within sight of the shore. Populations were vastly reduced by intensive harvesting during the active years of the whaling industry. Today, instead of hunting them, people often watch these acrobatic whales for pleasure.
