Abstract
The distribution and habitat of Scymnodon ichiharai Yano & Tanaka, 1984 (Squaliformes: Somniosidae) are reviewed, with reference to four specimens (957–1276 mm TL) from Sagami (fi rst specimen-supported record) and Suruga Bays, southern Japan, in addition to previous records of the species. Scymnodon ichiharai inhabits steep seafl oor topography in depths of 400–1300 m, and is distributed from the northern Pacific Ocean (Sagami Bay) to Taiwan and the Andaman Islands (Indian Ocean).
