Caribbean Sea

Four types of endangered sea turtles feed and mate among the corals of the Caribbean. Rising sea levels and temperatures, acidification of the oceans, and extreme storms could erode the beaches where the females nest and could threaten the coral reefs upon which the turtles depend. Since temperature affects the gender of turtle hatchlings, scientists fear a decline in male turtles, which could threaten the survival of the species.
