Why are penguins black and white?

The main source of this prey is actually krill in the ocean, so penguins need to hunt in the ocean. But there are natural enemies in the sea, such as seals. In fact, the black and white of penguins mainly plays a protective role.

Because when the seal at the bottom of the sea looks up, the penguin's belly is white, which is similar to the color reflected by the sea and plays a protective role.

On the other hand, its back is black. Looking from the air to the bottom of the sea, many oceans are dark. Sometimes when there is seaweed on the ground, it feels like a piece of black in the sea, so the penguin's back is black at this time, which also plays a protective role.

The world's first golden penguin was found in Antarctica.

Recently, a Belgian photographer shared a group of photos of penguins he took on 20 19. A group of photos of golden penguins quickly became popular. The photo shows that this golden penguin's feathers are not black, which is different from the black and white of ordinary penguins. Foreign media said it was the first golden emperor penguin in history.

All golden, it looks beautiful. But experts say this golden emperor penguin is probably sick. Like human albinism, it cannot produce melanin.
