Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 104 - 115; Spine anali: 0; Raggi anali molli: 90 - 100. Differs from Paraplotosus butleri in having a shorter dorsal fin and shorter nasal barbels, rounded pectoral fin shape, fewer upper procurrent caudal fin rays, and fewer gill rakers. Differs from P. muelleri in having a shorter dorsal fin and smaller eye (Ref. 31103). Color highly variable, ranging from pale grey or yellowish brown to dark brown, nearly blackish, sometimes with pronounced dark mottling; generally whitish on belly and ventral part of head; fins brown to blackish, frequently darker than body (Ref. 31103).
Body shape (shape guide): elongated; Cross section: circular.
In tropical areas, inhabits clear and turbid coral reefs; usually found in areas with mixed sand, weed, and coral areas (Ref. 31103). May be seen resting on sand bottoms under ledges or around coral bommies (Ref. 31103). Adults solitarily or in small groups. Presumably nocturnal (Ref. 31103). Feeds on gastropod mollusks and crustaceans (Ref. 31103). Spines associated with anterior fins have potent venom (Ref. 9801).
