🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 67 - 72; Anal spines: 0; Anal soft rays: 51 - 55. Body brownish, 2 double or tripe ocelli above and below lateral line and 1 on posterior third of straight section of lateral line. Many dark spots and rings scattered on body and median fins. Pectoral fin on ocular side with 12-13 rays. Pelvic fins short based, subequal and sub symmetrical in position, posterior 3-4 rays branched.: short and / or deep.

🌀 Behaviour

Bothus lunatus is well-camouflaged as it lies on the sandy seabed, often partially submerged in the sediment. It is more visible when it swims, which it does in a series of short glides, remaining close to the rippled sand contours of the ocean floor. In the Caribbean, a small octopus, Macrotritopus defilippi, mimics these bursts of swimming activity, a behaviour which might afford it protection from predators large enough to take a bite out of a soft-bodied octopus but too small to tackle a rigid flounder. In the West Indies, Bothus lunatus largely feeds on fishes, which make up 85.7% of its diet by volume, and particularly on herrings in the genus Jenkinsia and the bigeye scad (Selar crumenophthalmus). Another 11.4% of its diet consists of mantis shrimps and 2.9% of octopuses. Bothus lunatus is believed to be an ambush predator, lying concealed on the seabed before darting out to catch any unwary prey that moves too close.
