Moray eel jaw anatomy In addition to the presence of pharyngeal jaws, morays' mouth openings extend far back into the head, compared to fish which feed using suction. In the action of lunging at prey and biting down, water flows out the posterior side of the mouth opening, reducing waves in front of the eel which would otherwise displace prey.
The jaws of the Kidako moray, or moray eels in general, hold a dual-jaw system for feeding. [10] They primarily use the oral jaws to deliver prey into the esophagus with sharp and piercing teeth. The teeth are curved backward and point towards its throat to avoid prey coming back out of its mouth. [ 13 ]
Most fish species with pharyngeal teeth do not have extendable pharyngeal jaws. A particularly notable exception is the highly mobile pharyngeal jaw of the moray eels.These are possibly a response to their inability to swallow as other fishes do by creating a negative pressure in the mouth, perhaps induced by their restricted environmental niche (burrows) or in the air in the intertidal zone.

The hookjaw moray, bowmouth moray, or Bayer's moray (Enchelycore bayeri) is a moray eel of the family Muraenidae. It is found throughout the Indo-Pacific as well as in the Red Sea. [1] [2] Like other members of the genus, the hookjaw sports curved jaws and rows of large, dagger-like teeth.
English: Moray eels have two sets of jaws: 1) the oral jaws that capture prey; and 2) the pharyngeal jaws (similar to the jaws of the monster in the movie Alien) that advance into the mouth and move prey from the oral jaws to the oesophagus for swallowing.
Gymnothorax melatremus, the blackspot moray, dirty yellow moray or dwarf moray, is a moray eel from the Indo-Pacific East Africa to the Marquesas and Mangaréva, north to the Hawaiian Islands, south to the Australs islands. It occasionally makes its way into the aquarium trade but still being rare to find.
Other common names include conger, spotted eel, red moray, speckled moray, white cong, white jawed moray, white-chinned moray and white-jawed moray eel. Spotted eels have a long snake-like body, white or pale yellow in general with small overlapping reddish brown to dark-brown spots. They are commonly 60 cm (24 in) in length and can grow up to ...
The giant moray is carnivorous and nocturnal, hunting its prey within the reef. It is known to engage in cooperative hunting with the roving coral grouper ( Plectropomus pessuliferus ). [ 7 ] These two fish species are complementary hunters: While the eel hunts in the reef, it may scare prey up and out of the reef, leaving them to be eaten by ...
