Mouth position

terminal

Distinctive features

Elongated, snake-like body, Absence of pectoral and pelvic fins, Continuous dorsal, caudal, and anal fins, Small, conical teeth, Prominent anterior and posterior nostrils, Distinctive spotted pattern covering the entire body

Dorsal fin

Originates just behind the head and runs continuously along the back, merging with the caudal and anal fins.

Identification Tips

1. 1

   Coloration and Spotting

   Look for a light-colored body (tan to yellowish-brown) covered with numerous, irregularly shaped dark brown to black spots. The spots are generally smaller and more numerous than in some other spotted moray species.

2. 2

   Body Shape

   Its slender, elongated, and snake-like body is typical of moray eels. It can reach a maximum length of about 100 cm (39 inches), though most commonly observed specimens are smaller, around 60 cm (24 inches).

3. 3

   Fin Structure

   Note the absence of pectoral and pelvic fins, and the continuous dorsal, caudal, and anal fins that form a single fin fold around the posterior part of the body.

4. 4

   Head and Mouth

   Observe the relatively small head with a pointed snout and small, conical teeth. The anterior nostrils are tubular, and the posterior nostrils are simple pores.
