Biologists document surprising differences among deep-sea animals at hydrothermal vents
Like the boroughs of New York City or the arrondissements of Paris, deep-sea communities are turning out to have a strong local flavor.
In the waters off Antarctica at the southernmost seafloor vents where hot water percolates from below, piles of hairy crabs swarm in the thousands. In the middle of the Indian Ocean lives a motley collection of creatures never before seen together. And south of Cuba, at the world’s deepest vents, shrimp rule.
