Jeweled Moray Eel
The Jeweled Moray Eel, scientific name Muraena lentiginosa, is a species of moray eel that can be found in the tropical Indo-West Pacific region. This eel gets its common name from the beautiful pattern of jeweled markings that cover its body.
These eels have a slender, elongated body and can grow up to 60 centimeters in length. They are typically brown or black in color, with irregular spots or blotches of yellow, white, or orange that give them their distinctive “jeweled” appearance.
Jeweled Moray Eels are nocturnal creatures, hiding in crevices or caves during the day and prowling their territory at night in search of prey. They have excellent senses of smell and can detect food from a distance. Their diet consists mainly of small fish, crustaceans, and other marine invertebrates.
