Abstract
The crown of thorns, a conspicuous morphological feature among water fleas of the Daphnia atkinsoni species complex (Crustacea: Cladocera), is considered to represent a species-specific trait. However, our study, initiated by the analysis of sequence variation in 2 mitochondrial genes, shows that this feature is phenotypically plastic and is induced by chemical cues released by Triops cancriformis, the tadpole shrimp (Notostraca).
