How can you tell that the yeti crabs are “thriving”?

Gathered in heaps around the thermal vents, white

crabs wave their claws together in unison. Dubbed “yeti crabs”

for their hairy chests and legs, these creatures are new to science.

And they are clearly thriving, with up to 600 “yetis” living on each

square meter (about 11 square feet) of their favored real estate.

What do they eat? Scientists aren’t sure but conjecture that mineral eating bacteria might grow on the crabs’ hairs and that the crabs

might scoop up the bacteria

for me i cant do homework without music, so, i guess i would say faster with it, than without it. for me at least.

what is the question you are trying to ask here
