Abstract

Since 1976, Amazonian manatees have been examined either alive or through necropsies as part of a long-term program to rescue and rehabilitate orphan manatee calves whose mothers were either victims of illegal hunting or accidental catch in fishing nets in the Brazilian Amazon region. Rescued manatees have been found to have several types of diseases, but to our knowledge, there is no record of a congenital anomaly of the face, known as an oral cleft, in Amazonian manatees. In this paper, we report the occurrence of an oral cleft in an Amazonian manatee calf, describing the clinical evaluation and discussing the potential causes.
