It’s all fun! Jupiter, Florida has the second highest nesting population in the world. That means divers are likely to encounter sea turtles whenever they dive, but particularly from March to October during breeding and nesting season. Among the many things you’ll learn about sea turtles is how to identify the three species commonly found along the Treasure Coast—green, loggerhead, and hawksbill. A fourth species, the loggerhead, also nests in the area, but is far less common.
