Kiwa tyleri, the "Hoff crab", is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS James Cook, owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David Hasselhoff. The 2010 expedition to explore hydrothermal vents on the East Scotia Ridge was the second of three expeditions to the Southern Ocean by the UK led research consortium, ChEsSo (Chemosynthetic Ecosystems of the Southern Ocean).
