Snowflake Eel
Echidna nebulosa · also called clouded moray
Crushing a crab shell with blunt, molar-like teeth rather than the sharp points found in many of its relatives, a snowflake eel emerges briefly from a reef crevice, its white, black-speckled pattern resembling scattered snowflakes across the rock.
Overview
The snowflake eel, Echidna nebulosa, is native to ocean and coastal reef habitat across the Indo-Pacific region. Its distinctive crushing teeth suited to hard-shelled prey, striking snowflake-patterned skin, and relatively manageable temperament make it one of the more popular and visually recognisable moray eel species kept in aquariums.
A moray built for a different kind of meal
While many moray eels rely on sharp teeth to seize slippery fish, the snowflake eel instead carries blunt, crushing teeth suited to a diet of crabs and shrimp, a specialised toolkit that sets it apart from most of its sharper-toothed relatives.
Status
Least Concern, remaining widespread across suitable reef habitat throughout the Indo-Pacific region.
Snowflake Eel: common questions
Why does the snowflake eel have blunt teeth instead of sharp ones?
Its rounded, molar-like teeth are adapted for crushing the hard shells of crabs and shrimp, its main prey, a different toolkit from the sharp, piercing teeth many other moray eel species use to catch fish.
Why is it called the snowflake eel?
It has a white body covered in black, blotchy speckling that resembles scattered snowflakes, a pattern that gives the species its common name.
Is the snowflake eel a good choice for home aquariums?
It is considered one of the more manageable moray eel species for aquarium keepers, thanks to a relatively calm temperament and manageable size compared to many other moray species.
Where is the snowflake eel found?
It is native to ocean and coastal reef habitat across the Indo-Pacific region.
