List and iconography of the Oliva species found at low tide on some beaches of Bali and Gili Trawangan island (Indonesia). Shelling trip report.

During recent years the idea that the species belonging to the Genus Oliva mainly live in the intertidal zone has been definitively rejected. Nowdays we know that each species shows different behaviours chosing to live at different depth. In my last trip to Bali and Gili Trawangan islands in September 2011, I have checked what Oliva species were present in the intertidal zone and if the specimens found in those beaches were adult, juvenile or both. Moreover, each species found was photographed in its habitat and some specimens were collected. The olives were found both by following their tracks and by baits (small pieces of squid).
