季3 · 集 3 — Costa Rica: Sky to Sea · 2020-04-20

Perched between the Pacific Ocean and the Caribbean Sea lies Costa Rica: a tropical corridor brought to life by moisture-laden trade winds, raging rivers, and active volcanoes that simmer ominously. Together, they make up a fertile paradise of cloud forests that are home to green iguanas, sloths, and aptly named howler monkeys. The startling diversity extends to the surrounding coastal waters, where the mangrove forests provide an unlikely nursery to one of the ocean's most exotic predators: the hammerhead shark.
