A new vent limpet in the genus Lepetodrilus (Gastropoda: Lepetodrilidae) from Southern Ocean hydrothermal vent fields showing high phenotypic plasticity
The recently discovered hydrothermal vent ecosystems in the Southern Ocean host a suite of vent-endemic species, including lepetodrilid limpets dominating in abundance. Limpets were collected from the chimneys, basalts and megafauna of the East Scotia Ridge segments E2 and E9 and the Kemp Caldera at...
