We thank the submersible pilots and crews of the R/V Atlantis II/Alvin, Nadir/Nautile, Yokosuka/Shinkai 6500, and M/V Seward Johnson/Johnson SeaLink for their invaluable assistance. Our special thanks go to P. Chevaldonné, J. Childress, C. Fisher, D. Fornari, R. Gustafson, I. Jonasson, C. Moyer, M. Segonzac, V. Tunnicliffe, C. L. Van Dover, W. Wakefield, and A. Williams for assistance in obtaining specimens and thoughtful discussions. Johnson SeaLink dives were supported by NOAA NURP through the National Undersea Research Center at UNCW to C. Fisher. This is contribution No. 99-1 of the Institute of Marine and Coastal Sciences, and New Jersey Agricultural Experiment Station Publication No. 199, supported by state funds and by NSF Grants OCE9217026, OCE9302205, OCE89-17311, and BMBF No. 03G0094A to Freiberg University of Mining and Technology.

N2 - The evolutionary history of deep-sea shrimp (Caridea: Bresiliidae) inhabiting deep-sea hydrothermal vent and hydrocarbon seep environments was assessed using the mitochondrial Cytochrome c Oxidase subunit I (COI) gene (600 bp). Phylogenetic analyses (parsimony, likelihood, and neighbor-joining) recovered three distinct clades (A, Rimicaris/Chorocaris/Opaepele; B, Alvinocaris; and C, Mirocaris) consistent with higher level taxonomy based on morphology. However, robust phylogenetic results suggested that Chorocaris is paraphyletic and that Mirocaris fortunata and M. keldyshi may not be genetically distinct. A Kishino-Hasegawa likelihood approach was used to test alternative phylogenetic hypotheses based on biogeography and morphology. Evolutionary relationships of vent-endemic shrimp species did not appear to be correlated either with their extant biogeographic distribution or with the history of sea floor spreading. Additionally, COI data suggested that these vent-endemic organisms are not remnants of a Mesozoic vent assemblage; instead, they radiated in the Miocene.
