Sturgeons are called scavengers probably because sturgeons have strong hunting abilities and can easily clean up edematous food residues. Scavengers also specialize in eating food scraps at the bottom of the water. But sturgeons are not scavengers, they are two different species.

The difference between sturgeons and scavengers:

1. Different subjects: Chinese sturgeons are Chordata, teleost class, Acipuriformes, Acipensidae, Acipenseridae The scavenger is a fish of the genus and species of Sturgeon, and the scavenger is a fish of the phylum Chordata, class Actinopterygii, order Siluriiformes, family Onidae, genus Hypostome, and species of Catfish. There is a big difference between the two varieties.

2. Different shapes: Chinese sturgeons are spindle-shaped, their heads are pointed, and their snouts are relatively long. Their body surface is covered with five lines of scales, which are hard and large. The scavenger fish has a streamlined body, relatively small eyes, and a mouth at the bottom of the body.

3. Different habits: Chinese sturgeons mainly live in rivers and offshore waters. They like to move underwater and are migratory and semi-migratory. They mainly feed on small fish, shrimps or underwater microorganisms, and are carnivorous fish. Although scavengers also move at the bottom, they mainly live in streams and lakes and like to feed on algae and moss.
