How do moray eel protect itself?

Why is a moray eel an amazing animal?
The moray eel has an extraordinary pair of hidden chompers that it uses to attack its prey. Within its esophagus are two concealed pharyngeal jaws that help the moray eel seize its victim. Unlike most fish that use suction to consume their food, the moray goes through two steps.
Why do eels have mouth open?

How do eels eat their food?
These eels eat by scooping up prey in their large, open mouths. Because they have very small teeth, these eels generally feed on smaller prey, but they can consume larger creatures if necessary.
Are moray eels poisonous to eat?
Moray eels can accumulate very high ciguatoxin (CTX) levels in the flesh and particularly the liver. Therefore, even the smaller ones can be toxic and the consumption of an average portion (particularly liver) can result in severe or fatal ciguatera.
How long can a moray eel go without eating?

What is the purpose of pharyngeal jaw?
Pharyngeal jaws come equipped with powerful muscles and very plastic teeth, by which I mean that the morphology of the teeth can be modified in response to the prey items being eaten.
