板鰓亜鋼(サメとエイ類) (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Somniosidae (Sleeper sharks)
Etymology: Somniosus: Latin for sleepy, reflecting Lesueur’s surmise that these sharks are slow or sluggish because of their relatively small fins (hence the name sleeper sharks) (See ETYFish); rostratus: Latin for beaked, referring to its elongated rostrum (See ETYFish).

背面の脊椎 (合計) : 0; 肛門の骨: 0. Diagnosis: Somniosus rostratus is distinguished from S. longus in having overall length of second dorsal shorter than first dorsal fin 76-88% (vs. almost equal 91-100%); horizontal diameter of eye less than 37% (mean 33%) of length from snout tip to eye (vs. >37, mean 46%); number of tooth rows in upper jaw 53 (vs. 56-57); and spiral valve counts 23 (vs. 26-27) (Ref. 50224).
A rare species (Ref. 26346) found on outer continental shelves and upper slopes (Ref. 247). Probably feeds on deepwater bottom fishes and invertebrates (Ref. 247). Ovoviviparous (Ref. 205), length at birth 21-28 cm TL (Ref. 26346). Utilized as fishmeal and possibly as food fish (Ref. 247).
