In this study we used geometric morphometrics to describe qualitatively and quantitatively phenotypic plasticity of Synura echinulata silica scales cultured at four combinations of light intensity and temperature. Relative warps analysis revealed that the most important morphological trends were the disproportionality of distal and proximal parts of the scale, and the extent of the anterior labyrinthic pattern. All the groups of scales investigated differed significantly in shape. Silica scales of S. echinulata exhibited considerable environmentally induced plasticity, but taxonomically relevant characters remained unchanged.
