Solemyidae is a family of bivalves in the order Solemyoida, the members are known as Solemyids . They are remarkable in that their digestive tract is either extremely small or non-existent, and their feeding appendages are too short to reach outside the shell . It has been shown that these clams harbour sulphur-oxidizing Bacteria intracellularly within their gill filaments. As chemoautotrophs, these bacterial symbionts synthesize organic matter from CO2 and are the primary source of nutrition for the whole organism . In turn, the animal host provides its symbionts a habitat in which they have access to the substrates of chemoautotrophy (O2, CO2, and reduced inorganic compounds such as H2S). Together, these partners create "animals" with novel metabolic capabilities.
