During the past 20 years, 49 species of Opistobranch mollusks have been recorded with the aid of SCUBA diving and underwater photography in the Adriatic Sea. We found that certain localities have higher biodiversity than others. Some species are considered rare and only present at certain localities in a limited time of the year, while others can be found through the entire year at different localities and are therefore listed as frequent. Scuba diving and underwater photography are valuable tools in studying biodiversity of opistobranch mollusks. They provide us not only with records of a certain species but also with some other data, i.e. type of their habitat, food, spawn, etc. In the paper we also report on the highly surprising find of the tropical species Halgerda sp. in the shallow waters of the island of Cres. To our best knowledge this is the only record of any Halgerda species in the Mediterranean Sea.
