Animals and Plants

The only mammals on the small land portion are introduced species, mainly rats. Dolphins are occasionally sighted in the Gulf of Mexico.
The park name refers to a reptile, the turtle, or "tortugas". The five species of sea turtles found in the Dry Tortugas region are green, loggerhead, Kemp's ridley, hawksbill, and leatherback. The park is the most used turtle nesting site in the region.
299 species of birds are known to be in the region at least part time. Relatively few are regulars, and only 7 are thought to nest here. The NPS has prepared a checklist of park birds.
Underwater plants including seagrass and algae are numerous. On the keys, palms and other plants typical of the Florida keys are present.
