Japanese sturgeon
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.[3] 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 could reach up to 3 m (9.8 ft) in length, and weight over 190 kg.[4] The species is considered to be critically endangered.[5]

Habitat and ecology
The Japanese sturgeon is benthic. The females mature at 9–10 years of age, and males at 7–8 years. They start to migrate in the autumn. They live for 65 years.[4]
gollark: I also added a small note to https://wiki.computercraft.cc/Gps.locate about the results not always being reliable, since GPS is kind of vulnerable to spoofing.
gollark: It's more of a general guide-type thing explaining how to set up GPS hosts than information on how to use `gps host` itself.
gollark: Er, libraries.
gollark: The https://wiki.computercraft.cc/Network_security, which was admittedly mostly done by me then edited a lot by Lignum, links to some encryption APIs.
gollark: I think there's precedent.
