As mentioned earlier in the "feeding behavior" section, one adaptation of the yeti crab species is the growth of its setae to farm bacteria in the species Kiwa (puravida). There is some variation regarding the different types and various states of setae. There are two different types of setae that are organized adjacent to one another. Rows of narrow and flexible setae enclose the rows of more restricted, thicker setae. Because females slightly deviate from the vent environment during egg fertilization and larval development, brooding females contain more deteriorated, brown setae, as a result of their reduced carapace health away from the vent environment.

An additional adaptation found in the species Kiwa (tyleri) is the formation of a spine on the propodus (the end of the crab leg). This is beneficial for yeti crabs because they help the crustacean to cling to steep chimneys of hydrothermal vents. The stout, compact build of the crab also helps it traverse the hydrothermal vent.
