Kiwa tyleri, the Hoff crab, is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica.

[1] 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.

[1] Phylogenetic analysis of the mitochondrial 16S ribosomal RNA gene and a range of other anomuran crustaceans, using Bayesian inference, places this species from the East Scotia Ridge as a sister taxon to Kiwa hirsuta, with a sequence divergence from this species of 6.45%, which is consistent for within-genus divergence in squat lobsters.

It has been hypothesised that these sulfur-oxidising bacteria, which fix carbon from the water by oxidising sulfides in the hydrothermal fluid, are a significant source of nutrition to the crabs.

[1] Other marine fauna, such as sea anemones (family Actinostolidae), gastropods Gigantopelta chessoia, a species of stalked barnacle (most likely of the genus Vulcanolepas), a pycnogonid close to the genus Sericosura, and a predatory seven armed starfish can be found living together with this species.
