Sturgeon Fish Appearance

Sturgeon Fish Appearance and Caviar Product

Sturgeon fish are members of the Acipenseridae family, predominantly inhabiting rivers, lakes, and northern marine environments.

1. Sturgeon Fish Characteristics: External Traits and Identification

Sturgeon fish possess several distinctive traits that differentiate them from other fish species. Notable external characteristics include:

Elongated, oval-shaped body: Sturgeon fish generally feature long, oval bodies that facilitate their movement in cold, deep waters.
Robust skin and protective scales: Unlike many fish, sturgeon are covered with bony plates or tough scales that serve as armor, safeguarding them from predators and challenging habitats.
Downward-oriented mouth lacking teeth: Sturgeon fish have a mouth that is oriented downward, adapted for foraging food from the seabed, and they do not possess teeth like other fish.
Sensory whiskers around the mouth: Sturgeon fish are equipped with whiskers or sensory feelers near their mouths, which assist them in locating food in the water.
Significant size: Certain sturgeon species, such as the Beluga, can reach lengths exceeding 5 meters.
