This video features a neck crab documented during Dive 1 of the Océano Profundo 2018 expedition. Neck crabs get their common name because the body is constricted just posterior to the eyes. All of the neck crabs used to be in the genus Podochela, but this genus has recently been split up. The crab in this video might be Coryrhynchus sidneyi, which uses ascidians (group of tunicates) to decorate itself. The ascidians may later grow and help to camouflage the crab. Notice the extended first walking leg of the crab in the video, which crabs of the spider crab group (superfamily Majoidea) use almost like an antenna.
