Gymnothorax flavimarginatus
Family: Moray Eels (Muraenidae)
Size: Up to 1.2 m (4 ft) | Common: 80 cm
Depth: 2 – 150m (6 – 490ft)
Distribution: Indo-Pacific and Eastern Pacific (Costa Rica to Ecuador, including Galapagos).
Identification:
A robust and heavily built eel, often looking quite grumpy.
- Color: The body is yellowish-brown, covered in dense dark mottling that looks like a leopard print. The front of the head is usually a distinct dark purple or blackish color.
- The "Yellow Edge": It gets its name from the bright lime-green or yellow margin that runs along the rear edge of the dorsal and tail fins.
- Eyes: They often have striking orange or reddish eyes.
Behavior:
One of the bolder eels on the reef.
- Temperament: They can be inquisitive and less shy than other species. They are known to hold their ground rather than retreat deep into holes.
- Hunting: Like most morays, they hunt fish and crustaceans at night, but they are occasionally seen swimming freely across the reef during the day.

More Than Kicking Your Fins
At Ankla Azul, diving is more than kicking your fins. It's patient teaching, sharp safety, and real care for the place we call home.
