A shrimp swarm gathers on the undersea volcano's summit in April 2009. Some of the crustaceans eat the fast-growing bacteria filaments that bloom around the hydrothermal vents.

These bacteria grazers, called Loihi shrimp, have previously been seen living only near a small, active underwater volcano in Hawaii.

At the Guam volcano, the shrimp have adapted tiny, garden-shear-like claws, which allow the animals to slice the filaments for easier consumption.
