This paper presents the results of an investigation into the diversity of echinoderms inside the Boka kotorska Bay, as well as their spatial and seasonal distribution. This area is characterized by a specific complex of physical-chemical parameters of the sea water and sediments, which make it a particular biotope. Regarding the biology of echinoderms as sessile and slowmoving animals, the environment has an important role in their distribution and abundance. Obtained results show the presence of 32 species, distributed over diverse kinds of sea bottoms and different depths. Statistical analyses of samples show very low seasonal differences. According to the bottom type, the highest average similarity is recorded from samples taken from Posidonia oceanica meadows and rocky bottoms.
