The term "Sturgeon" refers to several species within the family Acipenseridae, which includes the Lake Sturgeon and the White Sturgeon. These ancient fish are known for their elongated bodies, rows of bony scutes, and vacuum-like mouths. Sturgeons are bottom-feeders, consuming small fish, invertebrates, and algae. They can grow extremely large, with some species reaching over 12 feet in length and living for over a century. Sturgeons are critically important for their caviar, but many species are now threatened or endangered due to overfishing and habitat loss.Click here to read more about Sturgeon.
