This rather snuggly looking crustacean was discovered in 2005 in the South Pacific Ocean. Given the presence of a substantial quantity of silky blond setae, its discoverers were quick to dub it the ‘yeti crab’. The unusual little decapod reaches an average length of around fifteen centimetres (just under six inches) and lives around hydrothermal vents deep in the ocean. It is for this reason that the fur-like setae contain filamentous bacteria, which allow the creature to detoxify poisonous substances emitted in the water by vents. It has been speculated that the yeti crab may actually feed on such bacteria – but it is generally believed to be a carnivore.
