Recent research has uncovered new population data on the Fangtooth Fish, a deep-sea predator infamous for its grotesquely oversized teeth—proportionally the largest of any fish. Its menacing jaws and compact body make it a formidable hunter in the ocean’s inky depths. Despite its nightmarish looks, it plays a key role in the deep-sea food web.
