Abstract

The first case of abnormal cephalic horns in the California bat ray, Myliobatis californica was found in one male juvenile specimen caught in a gillnet by artisanal elasmobranch fishermen on the west coast of Baja California Sur, Mexico. The specimen had three cephalic horns, two in the cephalic lobes zone and one in the rostral middle zone which could be indicative of a morphogenetic plasticity in these taxa that may have facilitated the evolution of rhinopterid and mobulid species from a common myliobatid ancestor with a similar role of feeding in Mobulidae and Rhinopteridae subfamilies.
