Species of fish
The Japanese sturgeon or Amur sturgeon (Acipenser schrenckii) is a species of fish in the family Acipenseridae found in the Amur River basin in China and Russia. Claims of its presence in the Sea of Japan need confirmation.[5] The species has 11–16 dorsal, 34–47 lateral, and 7–16 ventral scutes. Their dorsal fins have 38–53 rays and 20–35 anal fin rays. They also have greyish-brown backs and pale ventral sides. The species can reach up to 3 metres (9.8 ft) in length, and weigh over 190 kilograms (420 lb).[6] The species is considered to be critically endangered.[1]
