First record of Sphaerodoridae (Phyllodocida: Annelida) from hydrothermal vents
Sphaerodoropsis anae n. sp. is described from sediments near active hydrothermal vents along the northern part of the Pacific Antarctic ridge, adjacent to the Easter Microplate. Two distinct features principally characterize Sphaerodoropsis anae n. sp., the presence of a well-developed proventricle,...
