Etymology: Paraplotosus: Greek, para = in the side of + Greek, plotos = swimming (Ref. 45335); butleri: Named in honor of W. 'Harry' Butler, who assisted in with the collection of many of the paratypes (Ref. 31103).
Environment / Climate / Range
Marine; reef-associated; depth range 0 - 5 m (Ref. 31103). Tropical

Max length : 32.5 cm SL male/unsexed; (Ref. 31103)
Morphology | Morphometrics
soft rays: 87 - 102. Differs from Paraplotosus albilabris and P. muelleri in having a tall, sail-like first dorsal fin and extremely long nasal barbels, which extend posteriorly to the basal third of the pectoral fin or beyond (Ref. 31103). Small juveniles have a unique coloration consisting of a black head and body with a broad white to yellow margin on the first dorsal fin and continuous dorsal-caudal-anal fin (Ref. 31103). Adults entirely black (Ref. 31103).
