Green Moray Eel

Green moray eels are permanent residents of the Vixen wreck, occupying portholes, gun emplacements, and the collapsed sections of the hull where they hunt fish and crustaceans at night. Their vivid green colouration comes not from pigment but from a yellow mucus coating over a blue-grey skin, an adaptation that may provide antibacterial protection in the warm, biofilm-rich wreck environment. Adults here regularly exceed 1.5 metres and are sufficiently habituated to divers to allow close approach.
