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

Unusual Color Changes in Animals

Scientists are puzzled by the appearance of a white Iberian lynx in Spain, as well as other animals that have changed color, such as howler monkeys in Costa Rica.

Some animals, like chameleons, octopuses, cuttlefish, and snowshoe hares, naturally change color, but the case of a white Iberian lynx is unusual. A female lynx named Satureja has lost her natural brown and orange tones, but 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 research to understand the role of environmental factors, such as exposure to chemicals, in these anomalies.
