Average chlorophyll concentration in the surface ocean (from mi-September 1997 to August 2007) from the ocean color sensor SeaWiFS (NASA). Subtropical gyres, in the center of the oceanic basins, are characterized by very low concentrations of chlorophyll a (dark blue) - Source : NASA's Earth Observatory (http:/earthobservatory.nasa.gov)

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.
