The female lays fairly large eggs (5 mm) in the summer. Like with conger eels and European eels, their flattened, transparent oval larvae are called leptocephali.
The moray eel is a predator that hunts shrimp, crabs, cuttlefish, octopi and fish, mainly at night. Its threatening appearance and sharp teeth have earned it a terrifying reputation. However, it never harms divers intentionally and only attacks when feeling threatened.
Contrary to preconceptions, it has no venomous glands, although its jaws are covered with a toxic mucus that is responsible for the rapid infection of the wounds that it inflicts.
