Its land dwelling namesake is
still at large, but scientists have discovered a third species of the
yeti crab. Meet Kiwa tyleri, a deep-sea crustacean that belongs to the yeti crab family.
Ecologist
and study leader Sven Thatje explored the hydrothermal vents in East
Scotia Ridge, Antarctica, using remotely-piloted submersible and
discovered a thriving community of yeti crab living more than 8,500 feet
under water.
"We knew immediately that we'd found something tremendously novel and unique in hydrothermal vent research," Thatje said as reported by National Geographic.
Thatje
noted that the Antarctic waters where the crabs live are so cold that
they're just above freezing. The liquid that spews out of the
hydrothermal vents, however, can reach 700 °F (400 °C). That means the
yeti crab has only a tiny space where the water temperature is just
right: too close to the vents and they'll fry. Too far and they'll
freeze.
That's why the crabs pile on top of each other, Thatje
said, "like beans in a jar, filling every available space." Some 700
crabs are found in just one square meter.
