Etymology: Cantherhines: Greek, kanthos = the outer or inner corner of the eye, where the lids meet, 1646 + Greek, rhinos = nose (Ref. 45335).
More on author: Rüppell.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 20 m (Ref. 9710). Tropical; 32°N - 32°S
Indo-Pacific: Red Sea south to South Africa (Ref. 4421) and east to southern Japan and southeastern Oceania. Eastern Atlantic: Gulf of Guinea, Annobon Islands, south coast of Africa (Ref. 3592). Replaced by Cantherhines sandwichiensis in the Hawaiian Islands (Ref. 37816).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 3592); common length : 15.0 cm TL male/unsexed; (Ref. 3467)
soft rays: 29 - 32. Can adopt three basic color patterns: mottled grey and brown, dark brown, or grey with a network of close-set polygonal spots. All have a small white spot at the rear base of the second dorsal fin and sometimes the anal fin.
Occurs on outer reef slopes to depths of 2 to more than 20 m (Ref. 1602, 48637), often silty habitats. Young float with loose surface weeds and adults are often with large Sargassum rafts during the wet season (Ref. 48637). Solitary. Feeds on benthic organisms (Ref. 30573). Somewhat secretive (Ref. 9710).
