Key identification features
- Thick, muscular, eel-like body reaching over 2 m in large adults, one of the bulkier reef morays
- Dark brown-to-black mottled or reticulated pattern over a yellowish base color that darkens with age
- Continuous dorsal fin edged in black with a bright yellow margin running the length of the back
- Pale yellow eye and a slightly protruding lower jaw lined with sharp conical teeth
- Head often paler and more uniform than the strongly patterned body, giving a subtly two-toned look
Common look-alikes
- Undulated Moray: lacks the yellow-rimmed dorsal fin edge and shows finer wavy lines rather than blotchy reticulation
- Giant Moray: grows even larger with rounder, more evenly spaced leopard-like spots and no yellow fin margin
- Laced Moray: shows a denser, lace-like network of thin connected lines rather than bold mottled blotches
Where you'll see one
Widespread across the Indo-Pacific, from the Red Sea to Hawaii and south to Australia, where it hides by day in reef crevices, caves, and rubble on coral and rocky reefs from shallow water down to about 45 m, emerging at night to hunt fish and crustaceans.
Frequently asked questions
How can I tell a Yellow-edged Moray from an Undulated Moray?
Check the dorsal fin margin: Yellow-edged Morays show a distinct bright yellow stripe along the black-edged dorsal fin, a feature Undulated Morays lack.
What size and shape should I expect when I see one?
Expect a heavy-bodied eel often over 1.5 m long, with a blunt head and a mottled dark-and-yellow pattern rather than clean, discrete spots or stripes.
