Etymology: Gastroscyphus: Greek, gaster = stomach + Greek, kyphos = curved, bent (Ref. 45335); hectoris: Named after Sir James Hector, natural historian and Director of the Colonial Museum (Ref. 9003).
Eponymy: Dr Sir James Hector (1834–1907) was a Scottishborn Canadian geologist who took his medical degree at Edinburgh and, as both geologist and surgeon, was part of the Palliser expedition to western North America (1857–1860). [...] (Ref. 128868), visit book page.

Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 6 - 8; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 6 - 7. Color uniform or blotched reddish to olive green or brown dorsally, paler ventrally. A bar of lighter color along the head between the eyes and a narrow horizontal dark stripe from the snout to the gill cover separating the darker dorsal pigment from the paler lower surface. Occasionally a variable row of white spots along the side of the body. Distinguished from other clingfish by its distinctive body form (robust and tapers abruptly behind the dorsal and anal fins).
Commonly amongst brown algae (Cystophora) in rock pools at the low tide level and subtidal areas. Sometimes found on seaweed exposed at low tide. Swims towards cover and positions itself like drifting algae (heads up tail down position, sculling with the pectoral fins) when disturbed.
