The day began with an exciting start in the Sea of Cortez – the distinctive diagonal blow of sperm whales was seen! As the vessel cruised closer, we were able to get an excellent view of these magnificent creatures. After the exciting morning of wildlife viewing, we cruised to Puerto los Gatos. While loading the Zodiacs, a group of dolphins swam past the stern of National Geographic Venture. The dolphins escorted the first few Zodiacs to the beach, bow riding with some Zodiacs and jumping out of the water next to the boats. We approached the sandy shore beneath the red sandstone rocks with our snorkel gear, ready to discover what lives beneath the surface. We spent out morning snorkeling from the beach, during which time we found sea stars, urchins, and colorful reef fish. Excitement grew on the return to shore, when an octopus was seen moving slowly along the sandy bottom.
