Sessile vestimentiferan tubeworms inhabit chemosynthetic environments, such as hydrothermal vents or methane seeps. The new species described here, Lamellibrachia judigobini sp. nov. and Escarpia tritentaculata sp. nov., both from seep-dwelling genera, were discovered at a unique ‘hydrothermal seep’ of the Mid-Cayman Spreading Centre. We show an incredible habitat flexibility of a single Lamellibrachia species and the genus Escarpia, and historic biogeographic connections to the eastern Pacific for L. judigobini and the eastern Atlantic for E. tritentaculata.
