Etymology: Plectroglyphidodon: Greek,plektron = anything to strike with, spur + Greek, glyphis = carved + Greek, odous = teeth (Ref. 45335). More on authors: Jordan & Evermann.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 0 - 3 m (Ref. 7247). Tropical
Eastern Central Pacific: known only from Hawaii.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 7247)
Adults are found in very shallow water in the surge zone of exposed rocky shores (Ref. 3921). Benthopelagic (Ref. 58302). Feed mainly on benthic algae and occasionally on small invertebrates (Ref. 3921). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
