Key identification features
- Massive, heavy-bodied eel, among the largest of all true eels, reaching well over 2 meters
- Uniform grey-brown to bluish-grey above, fading to white or pale grey on the belly
- Smooth, scaleless skin with a slimy texture
- Large mouth with thick lips and small, close-set teeth
- Dorsal fin begins close to, or just behind, the pectoral fins
- Pectoral fins present and rounded, unlike true morays
Common look-alikes
- Longfin African conger - separated by dorsal fin position, which starts noticeably farther back (behind the pectoral fin tips) in that species compared to the more forward dorsal origin of the European conger
- Moray eels - separated by the presence of pectoral fins in congers, which morays completely lack
Where you'll see one
European congers live around rocky reefs, wrecks, and boulder fields of the northeast Atlantic and Mediterranean, from shallow water down to several hundred meters. They den in crevices and holes by day, with only the head often protruding, and forage more actively after dark.
Frequently asked questions
How do I tell a European conger from a moray eel?
Check the sides of the head for pectoral fins - congers have them, while true morays never do.
What separates a European conger from a longfin African conger?
Look at where the dorsal fin begins relative to the pectoral fins: it starts farther forward in the European conger and farther back in the longfin African conger.
