Fluorescence in situ hybridization images from different ANME types. (A) ANME-1 cells in elongated rectangular shape (red) that inhabit the Guaymas Basin hydrothermal vent as a monospecific clade. Republished from reference 165 with permission from Springer Nature. (B) Aggregate of coccus-shaped ANME-2 (red) and Desulfosarcina/Desulfococcus (green) bacteria, an enrichment sample after 8 years from the Isis Mud Volcano in the Mediterranean Sea. The image was taken from http://www.mpg.de/6619070/marine-methane-oxidation and is republished with permission from Jana Milucka and the Max Planck Institute for Marine Microbiology. (C) Aggregate of large, densely clustered ANME-2d (green) and other (blue) bacteria obtained from a bioreactor enrichment. Republished from reference 61 with permission from Springer Nature. (D) Aggregate of coccus-shaped ANME-3 (red) and Desulfobulbaceae (green) bacteria inhabiting the Haakon Mosby Mud Volcano. Republished from reference 54 with permission. Scale bars, 10 μm.
