Snyder, 1909

Inu is a small genus of gobies native to the northwestern Pacific Ocean[1]. They are closely related to Luciogobius[2].This genus and Luciogobius have a lot of characteristics in common; dorsally-flat head, absence of first dorsal fin, finely segmented vertebrate and so on.[2] Due to this similarity, some scholar integrate this genus into Luciogobius, while some phylogenetic studies support its division with Luciogobius[3].

Alike Luciogobius, the species of Inu dwell in pebble beach or rocky shore, which provide a plenty of gravel-interstitial spaces.[2] However, it is often pointed out that species of Inu tend to avoid exposing to the air compared to Luciogobius.[2]

Species

There are currently three recognized species in this genus:[4]

  • Inu ama Snyder, 1909
  • Inu koma Snyder, 1909
  • Inu saikaiensis (Dôtu, 1957)
