The name "sturgeon" encompasses over two dozen species, and these remarkable fish can be found in various parts of the world, primarily in the Northern Hemisphere. Their distinctive features include elongated bodies covered with bony plates (scutes), a cartilaginous skeleton, and a deeply forked tail. Sturgeons are well adapted to a wide range of aquatic environments, from freshwater rivers and lakes to brackish coastal waters. Their migratory behaviors, spawning habits, and foraging strategies vary among species, but they share a common thread in their remarkable ability to endure and survive in diverse conditions. Their evolutionary success story is a testament to the slow pace of their genetic change, resulting in minimal morphological alterations over millions of years.
