Do crabs live underground?
The crabs usually dig burrows in moist patches of dirt and spend most of the day in hiding. At night, the crabs wake up and roam around as they hunt for food.
Do crabs live in shells?
True crabs have abdomens protected by hard shells. Hermit crabs have soft, exposed abdomens. To protect themselves, hermit crabs search for abandoned shells — usually sea snail shells. When they find one that fits, they tuck themselves inside it for protection and carry it with them wherever they go.
How deep in the ocean do crabs live?
These crabs live down to at least 3400 m (over 11,000 feet), and yet they have eyes.
Can you eat yeti crab?

Do yeti crabs stink?
Yeti crabs live near hydrothermal vents, which emit abundant quantities of hydrogen sulfide. Hydrogen sulfide is the noxious gas a cracked egg leaks after reaching the end of its useful existence. It’s the same substance that gives flatulence its disgusting odor.
Do crabs eat bacteria?
The bristles that cover the crab’s claws and body are coated in gardens of symbiotic bacteria, which derive energy from the inorganic gases of the seeps. The crab eats the bacteria, using comb-like mouthparts to harvest them from its bristles (see a video of this on our YouTube Channel).
How do crabs grow hair?
One last interesting tidbit of information about crustacean exoskeletons: They do not grow, and thus must be molted as the animal gets bigger. And since the setae are part of the exoskeleton, they too are molted. This means that a crab gets new sensory setae every time it molts its cuticle.
Which body part helps the yeti crab catch food?
The distinctive “hair” on their bodies that gives them their name is scientifically known as setae, and serves as a “garden” where the yeti crabs’ favorite food — bacteria — grow. This difference in setae between the Antarctic yeti craband its two closest relatives, Kiwa puravida and K.
Why do yeti crabs dance?
Thurber thinks that the crabs perform their dance to make sure that the bacteria always have access to both oxygen from the ocean water and methane or sulfide from the seep. But by waving their arms, Yeti crabs mix water and seepage, keeping bacterial productivity high.
Who found the yeti crab?

What do the yeti crabs do to help the bacteria grow?
A thousand feet below the surface of the Pacific Ocean, a yeti crab “farms” a colony of bacteria on its claws. To help them grow, it waves its pincers over methane and sulfide vents, fertilizing the bacteria and making them good enough to eat.
Are yeti crabs actual crabs?
However, it was quickly nicknamed the “yeti crab”, because the long shaggy white hair on its claws bears an uncanny resemblance to the abominable snowman. Despite the name, yeti crabs are not true crabs, which all belong to a related group.

Are crabs blind?
Female blue crabs (Callinectes sapidus) are literally blind when they choose their mates, according to new research from Duke biologists Jamie Baldwin and Sönke Johnsen.
How deep can Crabs go?
Red and blue king crabs can be found between the intertidal zone and a depth of 100 fathoms (600 ft; 180 m). Golden king crabs live in depths between 100 and 400 fathoms (180–720 m, 600–2400 ft). The location of the pot is marked on the surface by a buoy, which is later used for retrieval.
