This part of Brazil is home to thousands of animals from the sea and land. Along this coast, various types of turtles have made this coast there nesting and breading grounds. Most of this habit has been used for construction but nearby is a preserve where you can see some of these turtles still alive.
The Projet Tamar (add link) has been working for many years to increase awareness and support to help save the turtles from over fishing and hunting , as well as stop further loss of their native habitat.
It is a government sponsored project and they have a very nice gift shop. Check for store hours before you leave. You will be asked to pay $2 each to help support the project
