Polar bears have hollow hair. Each hair is a clear hollow tube which reflects the light, making polar bears' fur appear white, though each hair is actually transparent.
Alpacas have hollow hair. They are indigenous to the Andes mountains and live in sub-zero climate. To accomodate this they have hollow hair to insulate and keep them warm. Similarly, llama have hair with a hollow core fibre.
Hollow hair, in fact, is an adaptation of animals which live in very cold climates. Reindeer, or caribour, also have soft hollow hairs, densely packed together.

How is a cast fossil different from a mold fossil?
if the original organism dissolves or decays, leaving a hollow in the rock, that is a mold. If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast. Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.
