Glasseye Snapper
Heteropriacanthus cruentatus
Sighting evidence at Cueva de los Peces, Bay of Pigs
Dense congregations of several hundred red-orange glasseye snappers fill the cave's twilight zone from wall to wall, hovering in stationary schools that pulse gently in the weak current. This species is nocturnal in open reef settings, but the cave's perpetual dim light allows the school to remain aggregated and semi-active throughout the day. They feed on small crustaceans and zooplankton that concentrate in the cave's mixing waters.
