Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 0; Ryggkotor: 185 - 189. Pale cream in color with variable pattern of large and small black spots with narrower white interspaces (Ref. 3972, 48635). Young with black saddles (Ref. 3972). Its behavior is similar to Myrichthys colubrinus and Leiuranus semicinctus.
Found in sandy areas of reef flats, lagoons, and seaward reefs; living buried in the sand. May aggregate in large numbers under a light at night (Ref. 9710). Sometimes fully exposed when searching for prey (Ref. 30874). Feeds on small fishes and crustaceans (Ref. 89972). Solitary and more common at night (Ref 90102).
