摘要

Silicoflagellates are present in the modern ocean, but they first appeared in the Cretaceous. Their siliceous skeletons consist of radial spines, a basal ring, struts, an apical ring or bar, and pikes. Tsutsui & Takahashi (2009) used a species-specific biometric program to take skeletal measurements of the species Distephanus medianoctisol in order to document its morphological variation. Their results showed that the radial spine length changed, depending on environmental conditions.
