Despite this hostile environment, these ecosystems support dense populations of macrobenthos which, with the help of chemoautotrophic endosymbionts, are fuelled by simple reduced molecules such as methane and hydrogen sulfide.

Deep-sea mussels (Mytilidae, Bathymodiolinae) often dominate at hydrothermal vents and cold seeps around the world.

The scale bar indicates 0.05 expected substitutions per site.

d, Phylogenetic tree of Mytilidae based on transcriptome data from representative genera/species.

c, Heat map of major annotated Pfam domains that are expanded in B.

platifrons, with multiple domains in a given gene being counted as one.

Using the lophotrochozoan tree as a reference, the time of divergence between B. philippinarum was estimated to be around 110.4 million years ago (Ma), with a 95% confidence interval of 52.4–209.7 Ma (Fig.

2b), which is close to the upper age limit of deep-sea symbiotic mussels (102 Ma) previously estimated using five genes.

A follow-up metaproteomic analysis of the gill of B.

platifrons shows methanotrophy, assimilatory sulfate reduction and ammonia metabolic pathways in the symbionts, providing energy and nutrients, which allow the host to thrive.

    Other bacteria make organic matter by reducing sulfide or oxidizing methane. Our knowledge of chemosynthetic communities is relatively new, brought to light by ocean exploration when humans first observed a vent on the deep ocean floor in 1977 and found a thriving community where there was no light.…

    Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide dissolved in sea water.…

    Chemosynthesis allows organisms to live without using the energy of sunlight or relying on other organisms for food. Like chemosynthesis, it allows living things to make more of themselves. By turning inorganic molecules into organic molecules, the processes of chemosynthesis turn nonliving matter into living matter.…
