The Beluga can live for well over 100 years and grow to over 7m (24ft) in length. While some scientists consider the Beluga to be the largest freshwater fish, others argue that it's not a true freshwater fish and give this title to the Mekong giant catfish.
Now classified 'endangered' due to over-fishing, it's roe (Beluga Caviar) is considered a delicacy. For more information see Sturgeon.
