It is part of the Ilhéus do Rombo islet group, located 4 kilometres (2.5 mi) east of Ilhéu Grande, the other main islet of the group, and 8 kilometres (5.0 mi) northeast of the island Brava.
The island is part of the integral nature reserve Ilhéus do Rombo,[1] famous for its seabird colonies.
[5] Notable endemic fauna found on the island include the Iago sparrow.
In the mid-1950s, W. R. P. Bourne observed females remaining in flocks while males began to take up locations on rocky slopes from which they could sing.
[6] A species of sponge Esperiopsis cimensis was found in the deep waters surrounding the islet.
