the southeastern edge of the
sepetiba bay is
an area where the fresh water biomes extending from the slopes
of the 'maciço da pedra branca' and the salt water habitats from
the
bay itself and the atlantic ocean beyond clash, creating a
unique area of great biological diversity.
it is a region crisscrossed by several straits
which divide it into several mangrove-covered islands, among
which is suruquai island.
