Habitat
This species inhabits coral reefs, rocky crevices, and lagoons in tropical and subtropical waters. It prefers depths from 1 to 50 meters, often in areas with abundant hiding spots like the Indo-Pacific regions including Hawaii and the Red Sea. Geographic preferences include warmer waters around islands and coastal areas.
Diet
The yellow-edged moray primarily feeds on small fish, crustaceans such as crabs and shrimp, and occasionally cephalopods like octopuses. It is a nocturnal predator that ambushes prey from hiding spots in reefs. Feeding typically occurs at night when it ventures out to hunt.
Behavior
Yellow-edged morays are solitary and territorial, often residing in the same crevice for extended periods. They are primarily nocturnal, hiding in reef crevices during the day and actively hunting at night. This species exhibits aggressive behavior when threatened, opening its mouth wide to display teeth, and it can be curious around divers but generally avoids direct interaction.
Conservation Status
Listed as Not Evaluated by IUCN.
