Answer
The creature pictured is an albino porcupine. Albinism occurs when an animal inherits a trait, or a set of traits, that interrupt melanin production (melanin is a pigment that determines the color of a mammal’s skin, fur, and eyes). Wikipedia says that 1 in 17,000 people are born albino; no data on porcupines could be found.
