bluntnose lizardfish; snakefish
A species of lizardfish (Trachinocephalus myops) found in coastal waters. The name 'snakefish' is also used, but 'bluntnose lizardfish' is the more precise common name.
Bluntnose lizardfish often hide in sandy seabeds.
When you observe a caught bluntnose lizardfish, you can see its sharp teeth.
The name likely combines 沖 (oki, 'offshore') and 鱛 (eso, 'lizardfish'), referring to a lizardfish found in offshore waters. The exact derivation is uncertain.
