The spotted ring penguin is the only penguin that lives in Africa. How did they become extinct step by step?
Penguin is a lovely creature living in Antarctica in people's memory, but there is actually a kind of penguin called spotted-billed ring penguin living in Africa. The place where they live subverts the original cognition of penguins. This penguin lives on the southwest coast of Africa, distributed on 24 islands from Namibia to South Africa, and entered Algoya Port in port elizabeth, so this group is not extinct at present.

First, the characteristics of the spotted ring penguin

In fact, the spotted ring penguin is the earliest penguin discovered by human beings because it is in Africa. 1488, a Portuguese sailor saw this strange animal at the Cape of Good Hope in South Africa for the first time 1. They stood in groups on the rocks on the shore, as if waiting for guests from afar. This penguin is only over one meter tall, and its feathers are very similar to those of other penguins, except that its tail and sides are black, but its abdomen is white. As a kind of flightless birds, their bones are hard and suitable for fast gliding underwater, and excess salt can be discharged from their eyes, which provides conditions for them to hunt underwater.

Second, the food of spotted ring penguins.

The food of the spotted ring penguin is similar to other gasoline, that is, all kinds of fish, mollusks and crustaceans. In drinking water, they can drink seawater directly, because the body can eliminate excess salt. They are good at diving at the bottom of the sea and can swim at a speed of up to 60 kilometers per hour. Although they can only lurk for about 5 minutes at a time, they can use these 5 minutes to quickly prey on the food they want.

Third, it is on the verge of extinction.

The killing of this penguin and the stealing of its eggs by human beings have caused serious harm to the reproduction of spotted ring penguins. In a short period of 30 years, the number of spotted beak-ring penguins decreased from 6.5438+0.5 million to 6.5438+0.45 million. Because penguin eggs are delicious, the collected penguin eggs are always eaten within a few days. Because the total number of ringed penguins has decreased by 90%, ringed penguins have been listed in the General Convention on International Trade in Endangered Wild Fauna and Flora in recent years.
