Eels are just eww, icky, ugly. And the Spotted White Moray Eel is no exception. If you see any eels during your dives, leave them alone. Though they are usually timid and hide, the morays are known to be aggressive. Their bites are far from lethal, but moray eels are toxic and their bites can be potentially dangerous if the wound becomes infected from their toxins. Plus, moray bites usually bleed heavily, which isn’t good for you if sharks are in the area.
