Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Eponymy: Dr Paul James Struhsaker (1935–2018) was a fishery biologist and ichthyologist. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / 深さの範囲 / distribution range
生態学
海 底生の漂泳性; 移住性ではない; 深さの範囲 99 - 302 m (Ref. 58302). Deep-water; 30°N - 18°N
Eastern Central Pacific: Apparently endemic to the Hawaiian Islands.
サイズ / 重さ / 年齢
成熟: Lm ? range ? - ? cm
Max length : 13.0 cm SL オス/雌雄の選別がない; (Ref. 7247)
背面の脊椎 (合計) : 14; 背鰭 (合計) : 13 - 14; 肛門の骨: 2; 臀鰭: 13 - 14.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Known only on the basis of specimens caught by a shrimp trawl in 99 to 183 meters (Ref. 7247). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
