sentence: Elapids use their venom both to immobilize their prey and in self-defense.
sentences_before: All elapids have a pair of proteroglyphous fangs that are used to inject venom from glands located towards the rear of the upper jaws. The fangs are the first two teeth on each maxillary bone, which are enlarged and hollow, and usually only one is in place on each side at any time. This action is therefore not as quick as with the viperids, that can envenomate with only a quick, stabbing motion. A few species are capable of spraying their venom from forward facing holes at the tips of their fangs as a means of defense.
