The two species of shrimp that live in this unstable environment are seen close up.

A close-up view of shrimp at NW Rota-1. The reason for the difference in color is not yet clear; however, one possibility is that the longer it has been since they last molted, the more material (perhaps sulfur or bacteria) that accumulates on their carapace (hard, upper shell).
