Habitat
This eel inhabits coral reefs, rocky crevices, and underwater caves in the Eastern Pacific Ocean, from the Gulf of California to the Galapagos Islands. It prefers depths of 1 to 50 meters, often in areas with abundant hiding spots to avoid predators and ambush prey. These environments include coastal waters around islands and continental shelves.
Diet
The Chestnut moray primarily feeds on small fish, crustaceans, and octopuses, using its sharp teeth to capture and swallow prey whole. It employs an ambush hunting strategy, hiding in crevices and striking at night when prey is most active. Feeding occurs mainly during nocturnal hours to minimize exposure to daylight predators.
Behavior
Chestnut morays are solitary and territorial, often claiming specific crevices or caves as their homes and defending them aggressively. They are primarily nocturnal, spending daytime hidden and emerging at night to hunt or explore. These eels can exhibit bold behavior when threatened, such as gaping their mouths to display teeth.
Conservation Status
Listed as Least Concern by IUCN.
