Habitat

Soldatov's catfish lives in Amur River (Ussuri) in Russia and China. It prefers water temperatures from 5 to 25 °C.

Description

This catfish is visually similar to the closely related Wels catfish. Soldatov's catfish has a large flat head. Its mouth is blunt and rounded, the upper jaw shorter than the lower jaw. Barbels are located on the upper jaw and chin. It has the following formula fins: dorsal six soft rays, anal 83–90 soft rays. The fish can live up to 20 years, and can grow to about 4 meters in length and weigh 40 kilograms.[1]

Threats

The Soldatov's catfish population is threatened by overfishing, habitat degradation and water pollution. Due to its localized distribution and the low population density, the population is now considered endangered.[2]

gollark: They *could* if they control the last pick, yes, hmmm.
gollark: Generate the outcome deterministically from the hashes of the inputs or something.
gollark: Perhaps this technology could somehow be adapted to the raffle.
gollark: That would make it explicitly net negative.
gollark: There are three outcomes, roughly:- it is fair, you win: you gain the total money- it is fair, you do not win: you lose what you spent- it is biased/evil/infohazardous and you lose money: you lose what you spent
