The topography with extremely steep escarpments of the Rocher de la Caravelle makes it completely inaccessible to man, whose presence is also prohibited. Beaten by the waves and covered with guano, it offers a refuge naturally protected by its distance of 1.8 miles (3 km) from the coast to several species of seabirds. The inventory of its avifauna drawn up in 2018 by the Biotope foundation made it possible to note the presence of five main species: the magnificent frigatebird, the brown booby, the brown noddy, the bridled tern, and the sooty tern. Frigatebirds and boobies do not nest on the rock but use it as a daytime and probably night roost. Although sooty terns frequent it only marginally, a significant nesting of bridled terns, a regionally threatened species, has been observed there. Of major interest for seabirds, the Rocher de la Caravelle is managed by the Conservatoire du Littoral (Coastal Protection Agency).
