Idiacanthus antrostomus Gilbert, 1890 .

Pacific Blackdragon. Males to 7.6 cm (3 in) TL ( Fitch and Lavenberg 1968) (Fujii in Masuda et al. 1984), females to 61 cm (24 in) SL ( Kamikawa 2017). Western Pacific Ocean north to Hokkaido, Japan (Aizawa in Nakabo 2002); Triangle Island (50°48’N, 129°06’W), British Columbia ( Milkova et al. 2016) to Chile ( Pequeño 1989). Depth: surface to 2,161 m (7,088 ft) (min.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California; max.: Castellanos-Galindo et al. 2006b), and perhaps to 4,100 m (13,448 ft) (Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California). The latter record of 4,100 m was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
