Appendiculaires - Ils vivent dans leurs filets
L’appendiculaire, proche ancêtre des vertébrés, fabrique des logettes aux filtres délicats à la fois résidence et filet de pêche.

Embryos and larvae
Drifting in the currents, embryos and larvae perpetuate the species and are food for multitudes.
Salpes - La vie enchaînée
Bien que d’apparence primitive, les salpes sont de proches ancêtres des poissons. Lorsque les algues abondent, les salpes prolifèrent en de longues chaînes d’individus clonés.

Les Dinoflagellés - Ceratium gravidum
Ceratium gravidum dont en voit parfaitement les mouvements d’un des deux flagelles.
Phytoplankton bloom observed in the Barents Sea (North of Norway) in August 2010 by the ocean color sensor MODIS onboard NASA satellite Aqua. Changes in ocean color result from modifications in the phytoplankton composition and concentration. The green colors are likely associated with the presence of diatoms. The shades of light blue result from the occurrence of coccolithophores, phytoplankton organisms that strongly reflect light due to their chalky shells - Source : NASA's Earth Observatory (http:/earthobservatory.nasa.gov)

Rosette used to collect seawater samples during a scientific cruise in the South Pacific Ocean. During the austral summer, the amount of chlorophyll a is so low that the water becomes deep blue, almost purple. (Photo : Joséphine Ras)
