Muraenidae - Moray Eels
Moray eels are efficient predators of fish and invertebrates on reefs and rocky shores in tropical and temperate regions. They lack both paired fins and scales; they have hard, pointed heads with many teeth; round gill openings, and a posterior set of nostrils set high on the head, usually between the small eyes. With such adaptations, they penetrate easily into the deep crevices of reefs in search of their prey. They hunt their prey both duing the day and night. Most species have daggerlike teeth for grabbing prey while some have flattened teeth for breaking up hard shelled invertebrates. Some morays grow to lengths of 3 meters, but most do not exceed 1meter.
