Green moray [Gymnothorax funebris]

The green moray, Gymnothorax funebris, is a moray eel of the family Muraenidae, found in the western Atlantic from New Jersey, Bermuda, and the northern Gulf of Mexico to Brazil, at depths down to 40 m. Its length is up to 2.5 m.

The green moray is a very large moray, uniformly dark green to brown. It is a benthic and solitary species occurring along rocky shorelines, reefs, and mangroves, usually found shallower than 30 m. Due to its large size and aggressiveness, the bites of this moray are particularly dangerous. It feeds mainly at night on fish and crustaceans. It is marketed fresh and salted, although large individuals are cigua-toxic. (text source: wikipedia)
