Sakhalin sculpin

The Sakhalin sculpin (Cottus amblystomopsis) is a species of amphidromous ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in eastern Russia to northern Japan. It reaches a maximum length of 20.8 cm.^[2] The Sakhalin sculpin was first formally described in 1904 by the Russian zoologist Peter Yulievich Schmidt with its type locality given as the Lyutoga River on Sakhalin.^[3] This species is sometimes placed in the subgenus Cephalocottus. The specific name is a misspelling of Ambystoma, the axolotl (Ambystoma mexicanus) combined with opsis, meaning "having the look of", and Schmidt described it as having a head that is "strongly dorsoventrally depressed, wide, nearly flat dorsally, abruptly sloping laterally, similar to the head of an axolotl" (translation).^[4]
