Primer registro del dinoflagelado Oxytoxum caudatum (Peridiniales: Oxytoxaceae) en el Golfo de California

Abstract

As part of a continuing microalgae monitoring program, phytoplankton samples were collected from 19 August 2014 to 25 February 2015 at a fixed sampling site in the southern part of the Bahía de La Paz, Mexico. The armored dinoflagellate Oxytoxum caudatum was observed mainly in net samples of phytoplankton. Study of live specimens did not show great variation in cell size or shape. Cells were 24-38 μm long and 12-16 μm wide (n= 30). This is the first record of O. caudatum in the Gulf of California.
