Northeast Brazil Shelf Marine
About the Area
The wide Abrolhos Bank of the east Brazil shelf forms a physical barrier to the Brazil Current, so upwelling and land conditions create even more diversity.
Taken together, these physical conditions create a diversity of shelf types, which in turn house a large variety of species.
This region provides a tropical breeding ground for Humpback whales (Megaptera noveangliae) and the smalleye hammerhead (Sphyrna tudes).
Several species of marine turtles exist in these waters, including the breeding Leatherback (Dermochelys coriacea) and Green turtles (Chelonia mydas), Hawksbill turtles (Eretmochelys imbricata), Olive ridley turtles (Lepidochelys olivacea), and Loggerhead turtles (Caretta caretta).
Overfishing, destructive fishing practices, and development threaten the reefs across this ecoregion. Recreational activities and tourism further damage the integrity of the reef ecosystem.

Are Green turtles herbivorous?
Adult green turtles are the only herbivorous sea turtles, feeding mainly on seagrasses or algae, mostly in the tropics and subtropics, but juveniles are assumed to be omnivorous to allow for their high growth rates. There is probably a gradual transition to herbivory, once the turtle is large enough to escape predators.
