Fig. 1. Map of the study sites in the Fernando de Noronha Arquipelago (FNA). The darker lines indicate the 20m and 50m isobaths. Inside the thinner line, there is the Marine Protected Area (MPA), while outside it, there is the Environmental Protection Area (EPA) for sustainable use. Both areas comprehend the land and insular shelf up to 50m isobaths. Circles indicate the sampling locations where focal-animal, ad libitum and intensive search methods were used; triangles indicate the sampling locations where only the intensive search method was used (see Material and Methods).

The figured photos were taken by one of us (CM) in 1981, with a preservation state that is closer to the original illustrations in Lydekker (1893), prior to the separation of the right and left rostral parts and pterygoids/palatines from the neurocranium and with more complete antorbital notches and right orbit. Scale bar: 200 mm.
