Slickheads or nakedheads are a family, Alepocephalidae, of deep-water fishes, most common below 1,000 metres (3,300 ft).^[1] They get their name from the lack of scales on the head. Similarly, the scientific name is from the Greek ᾰ̓- (a-, "not"); λέπος (lepos, "scale"); and κεφαλή (kephalē, "head"). It's mouth consist of 80 to 100 razor sharp teeth, and It has about nineteen genera with ca. 95 species.^[2] Some species bear photophores.^[2] In Japanese they are known as Sekitori Iwashi (関取鰯, "Massive Sardine").^[3]
