Skeleton shrimp

This strange-looking animal is a caprellid amphipod (also known as a skeleton shrimp) that lives on the mouthparts of deep-sea crabs. This particular animal was found clinging to a crab that MBARI researchers collected from the floor of Monterey Canyon, about 2,500 meters (8,200 feet) below the ocean surface. Inside the transparent body of this 8-millimeter (1/3-inch) female Caprella bathytatos you can see a clutch of eggs. Marine biologist Linda Kuhnz captured this pregnant amphipod using a camera attached to a microscope. Kuhnz spends hours using a microscope to find, catalog, and photograph the many tiny animals that live in seafloor sediment.
