Moray eel The dorsal fin extends from simply in the back of the pinnacle alongside the again and joins seamlessly with the caudal and anal fins. Most species lack pectoral and pelvic fins, including to their serpentine appearance.
The frame is typically patterned. In a few species, the internal of the mouth is likewise patterned. Their jaws are wide, framing a sticking out snout.
Most own huge enamel used to rip flesh or hold close slippery prey. A quite small quantity of species, as an example the snowflake moray (Echidna nebulosa) and zebra moray (Gymnomuraena zebra), in most cases feed on crustaceans and different hard-shelled animals, and that they have blunt, molar-like enamel appropriate for crushing.
Jaw Moray eel
The pharyngeal jaws of morays are placed farther again withinside the head and carefully resemble the oral jaws (entire with tiny “enamel”).
When feeding, morays release those jaws into the mouth cavity, in which they hold close prey and shipping it into the throat. Moray eels are the simplest recognised animals that use pharyngeal jaws to actively seize and restrain prey on this way.

Moray eel jaw anatomy
In addition to the presence of pharyngeal jaws, morays` mouth openings expand a ways again into the pinnacle, as compared to fish which feed the usage of suction.
Morays are opportunistic, carnivorous predators and feed in most cases on smaller fish, crabs, and octopuses. A noticed moray eel has been determined consuming a crimson lionfish with out harm.
Reef-related roving coral groupers (Plectropomus pessuliferus) were determined to recruit large morays to assist them hunt. The invitation to seek is initiated through head-shaking. This fashion of looking can also additionally permit morays to flush prey from niches now no longer available to groupers.

The moray eel may be determined in each freshwater habitats and saltwater habitats. The widespread majority of species are strictly marine, in no way getting into freshwater. Of the few species recognised to stay in freshwater, the maximum famous is Gymnothorax polyuranodon.
Although the moray eel can occupy each tropical oceans and temperate oceans, in addition to each freshwater and saltwater, the bulk of moray eels occupy heat saltwater environments, which comprise reefs.
Within the tropical oceans and temperate oceans, the moray eel occupies shelters, which includes lifeless patch reefs and coral rubble rocks, and much less often occupies stay coral reefs.
