The Sicchitello is the place where benthic life stands out, even if in summer, sometimes, the mucilagginous algae hide its charm by covering the rock and the coralliggeno. A multitude of brown and red algae populate the rock at the top of the pinnacles, with seasonal presence of sargasso; descending altitude gives way to red gorgonians (Paramuricea clavata), yellow gorgonians (Eunicella cavolinii) and various branches of Savalia savaglia. In a pelagic environment, that is, in open water, the show is unique: barracudas and ducts, as well as large amberjacks, are a practically constant presence, with large fish carousels unique in the Mediterranean. Occasionally, good sized snappers are also sighted, quite confident, while banded bream and salpe are almost ignored for too many things to observe. Black and pink damselfish make the atmosphere even richer close to the rocks, with their dense swarms that move in unison. Sicchitello Shoal is located in zone C of the Ustica Island Protected Marine Area​​.
