Host David Yetman and a group of international researchers including some from the Arizona-Sonora Desert Museum, traverse the famed Sea of Cortez. The Gulf of California as it is also known, once showcased the greatest marine diversity in the world. In this land of enhanced biodiversity, two different worlds come together –the terrestrial and the marine. On land, visit locals whose grassroots conservation efforts have helped revive the gulf’s endangered sea turtle population. On the beach, wade through the one of the area’s many tide pools to get up close and personal with sea cucumbers, flat worms, serpent stars, and sea anemones. On the water, watch the Bottlenose dolphins playfully accompany a tour of the region’s numerous enchanted desert islands.
