As one of the most bioproductive pelagic marine habitats on Earth, the deep ocean off Costa Rica’s southwestern Osa Peninsula is known for its spectacular whale and dolphin watching. During a dolphin tour 32 kilometers (20 miles) from Osa, tourists encountered a pod of about 60 pseudorcas (Pseudorca crassidens), also known as false killer whales. After following the pod for over an hour, the group stopped for a break, and this mother and baby stopped with them.
Pseudorcas are the third-largest members of the dolphin family and are closely related to orcas.
