HAbitat
All though Moray Eels are cosmopolitan creatures they greatly prefer warmer waters with coral reefs. The species are rarely found outside of these particular habitats. Many Eels live at depths of up to several hundred metres, where they spend most of there time concealed in crevices and alcoves, the mucus that the secrete from there skin can aid in the stability of coral. Around 90% of Moray Eels dwell in salt water provinces but there are a few who dwell in areas of brackish water ( areas where salt water and fresh water may be mixed ) such as the Fresh water Moray and the Pink lipped Moray Eel.
Predators
The main predators of the Moray Eel are other, larger Moray Eels, Barracuda, sea snakes and humans. The Moray Eels have a strange relashonship with the Grouper fish. Both of these creatures find it a benifit to hunt with each other however, Groupers are also the natural predators towards the Moray Eels.
Anatomy
Most of the species are more or less the same in terms of anatomy. Every species has a dorsal fin that extends from its head to the end of its tail. Most species also lack pectoral and pelvic fins which adds to the creatures serpentine appearance. There eyes are rather small, the Eels rely on there strong sense of smell to hunt there prey. The body is generally patterned. In some species, the inside of the mouth is also patterned. Most Moray Eels have two sets of sharp teeth that are perfect for tearing flesh and grasping slippery prey. The second set of teeth however only come into the mouth when the Eel is feasting on something, the second row of teeth also help bring the food down into the throat. Although Moray Eels don't like confrontation with humans, because of this extra set of razor sharp teeth larger Morays are capable of wouding/seriosly injuring humans. A relatively small number of species, for example the snowflake moray and zebra moray who feed on crustaceans and other hard-shelled animals, and have blunt, molar-like teeth suitable for crushing.
