GARATE-LIZARRAGA, Ismael; GARCIA-DOMINGUEZ, Federico; PEREZ-CRUZ, Beatriz  y  DIAZ-ORTIZ, Jesús Antonio. First record of Cochlodinium convolutum and C. helicoides (Gymnodiniales: Dinophyceae) in the Gulf of California. Rev. biol. mar. oceanogr. [online]. 2011, vol.46, n.3, pp. 495-498.

The naked marine dinoflagellates Cochlodinium convolutum and C. helicoides are reported for the first time in the Gulf of California. They occurred in seawater at 21-24.5°C. Cochlodinium convolutum was found in both bottle and net samples; its abundance ranged from 400-2200 cells L_1. A total of 96 specimens of C. convolutum and 23 specimens of C. helicoides were examined from the net phytoplankton samples. A short description is given for each species, and photomicrographs provide information about the main morphological characteristics.

Palabras clave : Dinoflagellates; phytoplankton; Mexico.
