After breakfast we sighted several sperm whales! Their distinctive, slanted blows, brown color, and their wrinkled appearance helped us identify the species. Sperm whales had been absent from the Gulf of California for many years, but now their food, Humboldt squid, have returned, and so have the sperm whales. Sometimes they swam close by the ship – it was truly exciting!

In the afternoon we were in Bahia Concepcion, near Isla Coyote. We had options to kayak, hike, or take a Zodiac cruise to search for wildlife visible on nearby islands.

Today ended quite magically, with a visit from more cetaceans. As National Geographic Venture departed Bahia Concepcion under darkness, common dolphins approached and swam alongside.
