Why might the armadillo's integument (shell and sparse hair) suggest susceptibility to temperature changes?

Answer

The large surface area of the shell and sparse hair may make them more susceptible to rapid temperature fluctuations.

The presence of sparse hair and a large bony shell surface suggests they may be more susceptible to rapid temperature changes compared to fully furred animals, possibly explaining their preference for burrows.
