A large Alvinocaris shrimp is surrounded by hundreds of smaller Opaepele shrimp that are grazing on a sulfur-coated cliff face. The Alvinocaris shrimp is aggressive in its interactions and has been seen to attack the smaller species. A basaltic andesite rock at NW Eifuku is covered with Shinkailepas limpets and thousands of their tiny egg capsules (white dots).  One side note about these limpets: like the mussels at NW Eifuku, these limpets had paper thin shells! A molten sulfur pond (five meters wide) churns in the bottom of a small crater at Daikoku (from the 2006 Submarine Ring of Fire expedition). This is a scanning electron micrograph of a microbial iron mat showing all the threads of ferrihydrite mineral left behind by the iron-oxidizing bacteria. Note that there are no bacterial cells present in this image, just the mineral remains. Image produced by Sean McAllister and Clara Chan, University of Delaware. Squat lobsters, shrimp, and scaleworms crawl on mussels. The squat lobsters appear “hairy” because of bacteria growing on their shells.
