The ampharetid genusAmphisamytha comprises nine known species of tube-dwelling worms. Seven species are known from deeper waters associated with hydrothermal vents and methane seeps in the Pacific and the Atlantic.
A molecular phylogeny of eightAmphisamytha species can be found in Stiller et al. (2013).
Amphisamythaspecies were only known from the Pacific Ocean but the genus' range was recently extended to the hydrothermal vents of the Atlantic Ocean.The molecular study by Stiller et al. (2013) showed that a species previously assigned to a different genus (Amathys) from Atlantic hydrothermal vents is a member ofAmphisamytha.
Deep-sea hydrothermal vents, methane seeps and shallow-water.
