Picãozinho

The name Picãozinho comes from the coral "peaks" that become visible at low tide. The main reef measures about 475 m by 202 m, totaling 95,950 m², and lies 1,500 m from the beach; it is presumed to be sandstone, formed by the consolidation of ancient beaches. Historically, the reef was a site of artisanal fishing. Since the mid-1980s it has received tourists, and for years visits took place without supervision, with fish feeding, trampling and boat anchoring. In the areas of intense visitation, a decrease in the diversity and distribution of corals has been recorded.

On dives it is possible to see various species of reef fish, corals, algae, mollusks and other invertebrates. Among the most frequent fish recorded on the reef are Abudefduf saxatilis, Stegastes fuscus, Sparisoma, Haemulon parra, Halichoeres brasiliensis and Acanthurus coeruleus. A 2015/2016 mapping recorded colonies of the corals Agaricia agaricites and Favia gravida on the northern and eastern edges of the reef, as well as the fire coral Millepora alcicornis.

The water tends to be clearer in the dry season, but diving is possible for most of the year. The best conditions usually occur when low tide falls in the morning, especially near the full moon and the new moon.
