#19 Beluga Sturgeon
Beluga Sturgeons are fascinating creatures! The Black Sea and the Caspian Sea are home to this long-living species of fish.
The oldest Beluga Sturgeon had a life of 118 years, and others regularly lived for around 90 to 100 years.
Unfortunately, their long lifespan did not prove to be fruitful for their survival since they are a critically endangered species.
To say that the Beluga Sturgeons are on the heavier side would be an understatement.
With the typical adult weighing approximately 2512 lbs, these fish are the third-largest living species of bony fish. They are also among the largest predatory species of fish in the world.
