This order is further divided into three suborders: the toothed whales, or Odontoceti, the baleen whales, or Mysticeti, and the Archaeoceti. The Beluga is a member of the Odontoceti. Its' family name is Monodontidae. Its genus name is Dephinapteres leucas, which means "dolphin without a fin." The species name leucas, means "white." The Beluga is derived from the Russian word Belukha. Beluga or "white whales" are not born white. They are gray and get lighter until approximately age six, when they are completely white. This lightening is caused by a reduction of melanin in the skin. Adults are yellowish-white to creamy white. They attain their whiteness upon reaching sexual maturity. Males reach sexual maturity at 8 or 9 years, while females become sexually mature at from 4 to 7 years of age. The male averages between 11.2 feet and 15.1 feet with a weight of about 3,307. The Beluga reaches its full sizes at the age of 10 years. The Beluga whale lives in the arctic and sub-arctic northern waters around the globe.
