 The Solitaire field is at a depth of 2,606 m (8,550 ft), and its dimensions are approximately 50 by 50 m (160 by 160 ft). The substrate rock is enriched mid-ocean ridge basalt. Scaly-foot gastropods live near the high-temperature diffuse fluids of chimneys in the vent field. The abundance of scaly-foot gastropods was lower than it was in the Longqi field. The Solitaire hydrothermal-vent community comprises 22 taxa, including: sea anemones Marianactis sp., crustaceans Austinograea rodriguezensis, Rimicaris kairei, Mirocaris indica, Munidopsis sp., Neolepadidae gen et sp., Eochionelasmus sp., bivalves Bathymodiolus marisindicus, gastropods Lepetodrilus sp., Eulepetopsis sp., Shinkailepas sp., Alviniconcha sp. type 3, Desbruyeresia sp., Phymorhynchus sp., annelids Alvinellidae genus and sp., Archinome jasoni, Branchinotogluma sp., echinoderm holothurians Apodacea gen et sp., fish Macrouridae genus and sp., unidentified Nemertea, and unidentified Platyhelminthes.
