The Equator coincides with a significant dispersal barrier for the vent palm worm Alvinella pompejana
(Desbruyeres & Laubier 1980, Hurtado et al.
Craig Cary of the University of Delaware in Lewes hovered in a submersible and inserted probes inside the tubes of a different Pacific-vent worm, Alvinella pompejana
In particular, [epsilon]-Proteobacteria were found to largely dominate the microbial communities associated with the vent polychaeate Alvinella pompejana and tubeworm Riftia pachyptila on the EPR at both 9[degrees] and 13[degrees] North (Cary et al.
Growth and phylogenetic properties of novel epsilon proteobacteria enriched from Alvinella pompejana and Deep-sea hydrothermal vents.
The discovery of 350 [degrees] C+ hydrothermal fluid pouring from "black smoker" chimneys in 1979 added a new dimension to hydrothermal vent biology: a tremendous diversity of microorganisms including Archaea growing above 100 [degrees] C, and Alvinella pompejana
worms living at temperatures up to 50 [degrees] C.
The tube worm species Alvinella pompejana
live around vent systems all along the East Pacific Rise, an undersea geological formation that stretches for thousands of miles.
