Despite years of collecting anecdotal and scientific information of cetaceans around Puerto Rico, the false killer whale (Pseudorca crassidens), was never reported. Here, we report the first stranding and sighting event to take place in Puerto Rico in January, and March 2013, respectively. Both events took place along the south coast of Puerto Rico. During the sighting, cooperative prey sharing tactics were observed when two animals appeared to attack a common dolphinfish (Coryphaena hippurus).
