Habitat
Grey morays primarily inhabit coral reefs, rocky crevices, and lagoon areas in the Pacific Ocean, especially around New Zealand, the Kermadec Islands, and nearby regions. They prefer depths from shallow waters to about 50 meters, where they can hide in caves and under ledges during the day. These habitats offer ample shelter and access to prey in warm, tropical to subtropical waters.
Diet
Grey morays are carnivorous predators that feed mainly on fish, crustaceans, and cephalopods such as octopuses. They employ an ambush hunting strategy, striking quickly from hiding spots, often at night when they are most active. Feeding behavior involves using their powerful jaws to grasp and swallow prey whole.
Behavior
Grey morays are solitary and territorial, typically occupying a specific crevice or cave that they defend aggressively. They are nocturnal hunters, emerging at night to forage while remaining hidden during the day to avoid threats. These eels exhibit curiosity towards divers but can become aggressive if provoked, often displaying an open-mouthed threat.
Conservation Status
Listed as Not Evaluated by IUCN.
