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.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 14; Raggi dorsali molli (totale) : 13 - 14; Spine anali: 2; Raggi anali molli: 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).
