a family of small deep-sea fish characterized by hinged skulls, fang-like teeth, and the ability to swallow prey much larger than themselves.
From the genus Chiasmodon with the taxonomic suffix -idae, which denotes a family-level classification in scientific nomenclature.
The Chiasmodontidae family shows how evolution optimized deep-sea hunting—in the darkness where food is scarce, a hinged jaw that swallows anything means you never have to say no to a meal!
