The arrowtooth grenadier (Ventrifossa atherodon) is a species of rattail. This is a deep-water fish found at depths of up to 950 m.[citation needed] It was originally recorded from the waters around Hawaii but has recently also been recorded near Taiwan, which suggests it has a far wider distribution than previously thought.[1]
