Animals possess up to ... 4 unique 'penis' on Earth

Echidna is a very special native porcupine animal of Australia, Tasmania and New Guinea. In addition to being one of the few representatives of mammals that lay eggs instead of giving birth, Echidna also owns four heads of the penis.

Of course, with such a special sexual organ structure, the mating process of this animal is also very different. Specifically, when having sex, the male individual will use 2 of 4 penis heads to ' penetrate' the female genitalia, and the sperm will also be released from the 2 ends of the penis. More specifically, the penis heads involved in the mission will be replaced one after the other.

In terms of other characteristics, Echidna possesses a round body with sharp, shaggy fur that is characteristic of a porcupine fur. Because Echidna's main food is ants and termites, their claws are very developed, to dig through the earth's nest.

Besides, in order to support hunting, Echidna also has an electric receptor receptor inside the muzzle, allowing them to sense electrical impulses emitted from ants and termites. Once he has located and opened the entrance to reach his prey, Echidna will use the ultimate weapon of a super-stick tongue to catch his 'meal' .

Echidna possesses a round body and sharp puffy feathers.

Because there are 4 very short and chubby legs, speed is not the advantage of this animal. Therefore, when encountering an evil animal, they often choose another defense solution to curl themselves into a ball of spikes, or hide themselves in the holes they dug up on the ground.

Until now, Echidna has existed for tens of millions of years. This makes them naturally become one of the oldest living creatures on Earth.
