Etymology: Plagiotremus: Greek, plagios = oblique + Greek, trema = hole (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 8 - 30 m (Ref. 30874). Tropical; 30°N - 50°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 9710)
Indo-Pacific: Red Sea and East Africa (to False Bay, South Africa, Ref. 4404) to the Line, Marquesan, and Tuamoto Islands, north to southern Japan, south to New Zealand and Rapa. Replaced Plagiotremus goslinei in the Hawaiian Islands (Ref. 37816).
Inhabit clear lagoon and seaward reefs (Ref. 9710), usually the lower surge zone to deeper areas. Hide in deserted worm tubes when alarmed (Ref. 1602). Feed by attacking other fishes and removing dermal tissue, mucus and sometimes scales; occasionally makes harmless 'attacks' on divers (Ref. 2334, 48636). It usually strikes from behind and quickly dives in the reef for cover to avoid punishment (Ref. 48636). Its wriggling swimming mode possibly mimics other non-scale eating species. Oviparous (Ref. 205). Eggs are demersal and adhesive (Ref. 205).
