Besides coloring the hair and skin, what other vital function does melanin support in ferrets?

Answer

Eye development and protection from light

Furthermore, it plays an active role in protecting the sensitive structures of the eye from excessive light exposure. The absence of melanin in the iris, characteristic of albinism, directly leads to photophobia, or sensitivity to bright light, underscoring melanin's importance in visual health.
