Pharyngeal jaws are a “second set” of jaws located within moray eels’ throats. When a moray eel captures prey with its primary jaws, it can use its secondary pharyngeal jaws to grab the prey and drag it down into its gullet for easy swallowing. They use these jaws to capture prey like venomous fish.
Q. Why do eels always have their mouths open?
Why do moray eels always have their mouths open? Most fish breathe by closing and opening their gill covers to force water over their gills. Moray eels don’t have gill covers, so they constantly open and close their mouths to breathe.

Q. Why do eels yawn?
(Brown notes that the sexes in eels look alike, with dissection the only sure method to tell males from females.) “People often asked why Dill appeared to be yawning or gaping,” says Brown. “That’s actually what morays do to move water and oxygen over their gills for breathing.
Q. Why do eels have so many teeth?
So structured, these teeth are specially designed to help prevent prey from backing out of the eel’s mouth, much like spike-strips in parking lots help prevent cars from backing out of entrance ramps. Unlike the moray eel, most fish capture and move prey into their throats by using suction.
Q. What eels are poisonous?
Many moray eel varieties also have toxins in their mouth mucous as well as in the layer of slime that covers their bodies, including a toxin called hemagglutinin that causes red blood cells to clump. Moray eels may also generate crinotoxins, which can destroy red blood cells.
Q. Are eels smart?
Eels have many traits that suggest a lively intelligence. They are known, for example, for going on hunger strikes in captivity, and they hunt cooperatively with groupers in the wild. On the other hand, they’re also famous for sudden and egregious acts of aggression.
Q. Do eels live in dirty water?
The American eel performs a yearly migration from fresh water lakes to the ocean and back. So they oscillate between being fresh water fish and salt water fish during their migration. They require ‘clean’ water. Moray eels are true eels live deep in the ocean all the time.
Q. How do you kill eels before cooking?
“To kill an eel, seize it with a cloth and bang its head violently against a hard surface. To skin it, put a noose around the base and hang it up. Slit the skin in a circle just beneath the noose. Pull away a small portion of the skin, turn it back, take hold of it with a cloth and pull it down hard.”
