In addition to the dense colonies of mussels at NW Eifuku, there are also the same two species of shrimp that we found at NW Rota-1 (the volcano we found to be actively erupting). However, at NW Eifuku the two shrimp species live in different habitats separated from one another, whereas at NW Rota-1 they are found together.
