L'Atalante basin
Below, in the brine, the number of cells is much lower than in the halocline. Extremophiles are most common, including some of the deep-sea hydrothermal vent archaea and bacteria. Eukaryotes are also found in l'Atalante, mostly ciliates (45%), dinoflagellates (21%) and choanoflagellata (10%).p360–381
