French Guiana, Awala-Yalimapo Beach. Leatherback & Green Turtles. Season: February- August. Unique because the Leatherbacks Turtles nest during day light at sunset, but there is little infrastructure and poaching is common.
México, Various Beaches, Yucatán Peninsula. Hawksbill Turtle. Season: May to October. Hawksbill shells are used to make combs and other trinkets. Hawks Bills are an endangered species. Harvesting Hawksbills is illegal in most of the world, but some amount of harvesting is allowed in Cuba, the Cayman Islands, the British Virgin Islands and Turks and Caicos. Even if harvesting Hawksbills is permitted it is illegal to bring Hawksbill products into most countries and unethical to buy Hawksbill products and thus encourage the trade. That said, the biggest threat to all sea turtles, including Hawksbills is habitat destruction.
