From the white Iberian lynx in Spain to the howler monkeys of Costa Rica: Why do animals change color?

Animal Color Changes: A Call for Research

Scientists are intrigued by the appearance of a white Iberian lynx in Spain, sparking questions about environmental factors and their role in animal color changes.

Certain animals, such as chameleons, octopuses, and snowshoe hares, naturally change color, but the case of a white Iberian lynx is unusual. A female lynx, known as Satureja, has lost her natural brown and orange tones, yet retained her unique black spots.

No one knows the reason for this striking change in coat color, which had already been observed in another lynx previously.

Researchers are calling for more studies to understand the impact of environmental factors, including exposure to chemicals, on these anomalies.
