The Yeti Crab
Physical features
The crab is a blind deep-sea crab whose legs are covered with long, pale yellow hairs.

These are the long pale hairs.On a baby the hairs would be really light pale
or even sometimes white.
These are the long pale hairs.Usually on a baby these long hairs are colored really light pale or even white.
Community
The yeti crab eats mussels and bacteria that grows on them, they are harvested. They live near hydrothermal vents.The males stay more closer to the hydrothermal steam vents to apparently feed on communities of bacteria on their hair lined bellies.
These are the hydrothermal vents.
Population
The yeti crab is growing in population even after it has been discovered and the population is growing really fast! the males mate and then the females go to more cooler water to produce eggs.The males are bigger than the females.
Thousands and thousands of yeti crabs.
The yeti crabs Ecosystem
The reason their existence is remarkable is that they were found on top of undersea volcanoes called hydrothermal vents, which pump out plumes of black and sometimes clear smoke causing temperatures to rise up to 380°C - hot enough to melt lead. With no sunshine there, they live in complete darkness but the creatures get their energy from breaking down highly toxic chemicals found in the smoke.

is covered in silky white setae (resembling fur), the thickest of setae being on the pincers. The crab is generally about 15 cm long. Besides the setae and the fact that it's white, the Yeti Crab looks like any other crab. It still has a shell, six legs and two pincers.
