The Mediterranean moray has an elongated, eel-like body and can reach a length of 1.5 metres (4 ft 11 in) and weigh over 15 kilograms. Its coloration varies from dark grey to dark brown with fine dark spots. The skin is slimy and without scales. The dorsal fin begins behind its head and continues to the caudal fin (fused with the anal fin).
Most species are found in tropical or subtropical environments, with only a few species (yellow moray) found in temperate ocean environments. Although the moray eel can occupy both tropical oceans and temperate oceans, as well as both freshwater and saltwater, the majority of moray eels occupy warm saltwater environments, which contain reefs.

Manchineel trees are often signposted as dangerous. William Ellis, ship's surgeon for James Cook on his final voyage, wrote: On the fourth, a party of men were sent to cut wood, as the island apparently afforded plenty of that article; amongst other trees they unluckily cut down several of the manchineel, the juice of which getting into their ...
Moray eels such as the Giant moray are only occasionally aggressive; most bites result from divers putting a hand into the hole in which the eel lives. Surgeonfishes have sheathed or fixed blades at the base of the tail which can inflict deep wounds (the yellow stripe on the Sohal tang pictured).
Eels are nocturnal and most of their feeding therefore occurs at night. [28] Having a keen sense of smell, eels most likely depend on scent to find food. The American eel is a generalist species which colonizes a wide range of habitats. Their diet is therefore extremely diverse and includes most of the aquatic animals sharing the same environment.
Many eel-like fish of the order Anguilliformes have toxic proteins in their blood which has to be destroyed with heat before eating. Moray eels also produce toxic mucus, and can store toxins in their flesh and organs. [3] The giant moray is a reef fish at the top of the food chain.
Muraena is a genus of twelve species of large eels in the family Muraenidae. This genus is common in the Mediterranean, and is abundantly represented in tropical and subtropical seas, especially in rocky parts or on coral reefs.
