Preferred habitat under a stone in grassland. Identification. Our specimen was identified as E. epinephelus based on: ventral scales 182, subcaudals 54, venter inmaculate, and scale pits present. Remarks. We found this species in the grassland habitat, where it was under rocks ( Fig. 10B ), near cultivated areas with evidence of the use of agrochemicals. As an escape strategy from predators, this species can flatten the body by contracting transverse muscles ( Fig.10A ).
