In the deep waters around the San Lorenzo group in the Northern Gulf of California we have had a couple of fascinating encounters with pilot whales. Some of them swimming upside down checking out Narama's bottom and others vocalising. The clip attached has the vocals of a group slowly travelling, the second sound bite is a different occasion when two groups met with far more excited calls. The pictures are a mix of Pilot whales, Long-beaked common dolphin, Bottlenose dolphin, Whale Shark, Sperm whale and Bryde's whale.
