4. Hoff Crab (Kiwa tyleri)

Discovered near hydrothermal vents in 2012, the Hoff crab stands out for its hairy, “chest”-like setae that amusingly evoke actor David Hasselhoff. This unique adaptation isn’t just for show—the crab uses its furry chest to farm bacteria, which it scrapes off for nourishment in the nutrient-scarce deep sea.
