Nature - Series 3 - The Sea of Cortez

The Sea of Cortez, off the coast of Mexico, is a whale and dolphin hotspot where the widest variety of cetaceans on earth can be found in one place. Along with close encounters with whales, Tessa McGregor also reflects on the prophetic words of Ed Ricketts and John Steinbeck in their book, The Log of the Sea of Cortez.
