title: First record of a bicephalic embryo of smalltail shark Carcharhinus porosus.
abstract: This study reports the first bicephalic embryo of smalltail shark Carcharhinus porosus, which was removed from a pregnant female in coastal waters of the tropical eastern Pacific Ocean. The observation suggested that although the individual's body was well formed, the malformation of the head would have affected it survival.
