Daphnia, a keystone group of freshwater crustaceans, exhibit a remarkable degree of phenotypic plasticity when exposed to predation risk. These adaptive responses include morphological ...

This is a mature Daphnia magna imaged under a microscope at 20x magnification. The photo was taken at the end of the 21 day exposure to sunscreen so that we could measure its body length. The ...

Daphnia is native to Lake Tahoe and makes up an important part of the lake's food web. In recent years, the Daphnia population dwindled as its main predator, the mysis shrimp, dominated.
