Water flea, Daphnia magna

Caption

Water flea, Daphnia magna, rougly 5mm across. Study results show that exposure to UV-filters over a 48-hour period prevented the fleas from navigating through their environment. Exposure over a 14-day period--similar to what might occur near popular beach areas--proved lethal for the tiny crustaceans.
