American Eel
Anguilla rostrata
Sighting evidence at El Tanque, Bay of Pigs
Slender individuals occasionally enter the cenote through the sea connection during their complex catadromous life cycle, sheltering in the halocline zone where they exploit both freshwater and marine invertebrate prey. Their presence indicates that the underground passages remain open and unblocked — an important measure of the geological connectivity of the system. Sightings concentrate between October and January when juveniles are migrating along the coast.
