A 1000-kg, 4.17-m-long beluga fish from the Volga River (National Museum of Tatarstan, Kazan, Russia) Among all extant bony fishes, the beluga sturgeon rivals the ocean sunfish (Mola sp.) as the most massive fish and is the second-longest bony fish after the giant oarfish (Regalecus glesne). It is the largest freshwater fish in the world.
The kaluga sturgeon is a massive fish, also known as the "river beluga". It has a triangular head with several bony plates.

The beluga sturgeon can take up to 20 years to reach maturity. The fish harvested for caviar are often nearly 900 kg (2,000 lb). The eggs themselves are the largest of the commonly used roes, and range in color from dark gray (almost black) to light gray, with the lighter colors coming from older fish, and being the most valued.

A rare type of caviar known as Imperial Caviar, from the Sterlet sturgeon (Acipenser ruthenus), a now nearly extinct species of sturgeon from the Caspian Sea, [3] is sometimes incorrectly labeled as Sevruga, as well as the even rarer Golden Caviar from the albino Sterlet, the caviar being yellow in color.
Monodontids have a wide-ranging carnivorous diet, feeding on fish, molluscs, and small crustaceans. They have reduced teeth, with the beluga having numerous simple teeth, and the narwhal having only two teeth, one of which forms the tusks in males. Gestation lasts 14–15 months in both species, and almost always results in a single calf.
