Another bit of information from Cozumel Insider:
"Turtle Season Begins
About 25 loggerhead turtle nests have been marked in the first 17 days of arrival of turtles to lay their eggs on the east coast of Cozumel. Commonly this kind of turtle arrives in the first five weeks of the season, and then is joined by the green turtle, which has been arriving in greater numbers each year to lay eggs. The hawksbill turtle is the most sought-after for its shell, and although this breed is frequently seen on Cozumel’s reefs, it lays its eggs on the coast of the Yucatan peninsula. In order to protect the turtles the police have closed the highway to traffic from 10 pm to six am, and military troops monitor the coast on foot. The consumption of turtle products is punishable by jail term and numerous fines and is considered a federal crime. "
