At night, a slender predator slips from the shadows of rocky crevices and underwater caves to hunt along Mallorca’s coast. This is the Mediterranean moray eel (Muraena helena), a secretive resident of local waters, found at depths of 5 to 50 metres and growing up to 1.5 metres long.
By day, the elusive moray rests out of sight. For divers and snorkellers, catching a glimpse of its head poking from a crevice — mouth slightly open, teeth on display, ready for its closeup — is a moment of fascination and a favourite photo opp.
Despite its fearsome appearance, the moray rarely threatens humans and attacks only when provoked. The danger comes if someone tries to touch it or force it out of its shelter: its bite is powerful, and thanks to bacteria in its saliva, infections are common.
Local guides offer simple advice: Admire the moray — but respect its space.
