One Cool Moment with a Ribbon Eel

Indonesia’s Underwater Jewel

Encountering a ribbon eel gliding through coral rubble is one of the most enchanting moments a macro diver can have. During a dive on a shallow reef slope, I paused mid-water column—hesitant to stir up the sand—and saw a slender snout slip quietly between the rocks.

The Creature

Ribbon eels are elongated, slender moray-eel relatives known for their vibrant blue body and contrasting yellow dorsal fin. Their long bodies allow them to slip partly into soft sediment, perfect for ambushing small fish.

The Habitat

In Indonesia’s coral reef zones, sightings are most likely in shallow to moderate depths (5–20 metres). These habitats combine loose rubble or sand with nearby reef structure for shelter.

Pro Tip

Use a wide-angle lens. Ribbon eels are long and may not fully extend from their hideouts. Use strobes at low power to avoid overexposing the vivid blues and yellows.

Quick Facts

Ribbon eels are relatively shy and non-aggressive. They may retreat or flick their heads if disturbed, but they are not known to pose danger to divers. It is best to observe without touching.

They are commonly found on sandy or rubble slopes near reefs, at depths ranging from approximately 5 to 20 metres.

Early morning dives or calm-water periods often offer the best chance. Good visibility and low current help make the subtle coloration of ribbon eels stand out.

      1. Apparently, the Northwest was one of Cousteau’s favorite dive spots. It helps to wear a dry suit, and the vis isn’t what you’d get in most warm water places, but there’s plenty to see in the right places.
