Etymology: Plagiotremus: Greek, plagios = oblique + Greek, trema = hole (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 1 - 10 m (Ref. 90102). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 2272)
(total): 7 - 8;
soft rays: 20 - 23. Pale grey body, dorsal fin with black submarginal stripe. Pectoral rays typically 12; large curved canine tooth posteriorly on side of lower jaw; interorbital pores 1-2; body depth about 8.0 in SL. Maximum size to 5.1 cm TL (Ref. 90102).
Adults are found solitary in coastal, lagoon, and outer reefs, 1-10 m deep (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). A mimic of Meiacanthus smithi (Ref. 9710).

Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00245 - 0.01178), b=3.05 (2.85 - 3.25), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
