Deepest-living crustacean

The greatest depth from which a crustacean has been recovered is 10,500 m (34,450 ft) for live amphipods from the Challenger Deep (Marianas Trench) in the west Pacific by the US research vessel Thomas Washington in November 1980. No species have been collected from a greater depth. However, according to Mark Carwardine's 2007 book Natural History Museum Animal Records, in 1960 an unidentified species of red shrimp was sighted at a depth of 10,913 m by Lt Don Walsh and Jacques Piccard from the bathyscaphe Trieste in the western Pacific Ocean's Marianas Trench, near the island of Guam.
