You Don’t See This Hairless Deer-Pig Every Day on a Farm
Based on current research, it is suggested that pigs, of which the wild babirusa is a member, might be the second closest terrestrial relatives to the dolphin after hippos. But, surely, these animals lost their hair long after their aquatic counterparts. Despite that, the reasons seem to be largely similar. It appears that in place of the hair, they developed extra fat layers to insulate against heat.
Besides that, they also roll in mud to help stay cool, as the other pigs do. However, the babirusa’s most unusual feature is its imposing tusks which have earned it the nickname “deer-pig.” The belief is these tusks are grown not as a weapon but as a defense to protect the face of males.
