Taxonomy Orseis grasslei (now Sirsoe grasslei) is the type species of Sirsoe but important genetic characterisation was lacking until Kroesche & Rouse (2025) reported molecular data for a specimen they identified as S. grasslei from the Pescadero Basin vents several hundred kilometres south of the type locality at Guaymas Basin. They stated that "A precedent for matching fauna at both sites comes from polychaete species to have been found at the Pescadero vents at 3700 m and those at ~2000 m in the Guaymas Basin. Zhang et al. described Ophryotrocha marinae from both sites in 2023 and provided molecular evidence to support this. Other annelids such as Branchiplicatus cupreus and Riftia pachyptila are also known from both sites." [details]
