Not long ago, several scientists accidentally caught a frilled shark about 1.5 meters long off the Portuguese coast of Algavi. It is a very primitive shark and one of the oldest living animals. It is said that it has lived on the earth for 80 million years. The wrinkled shark is very different from the ordinary shark in appearance, but it is somewhat similar to the eel.

Morphological characteristics The frilled shark is named after the frilled gill fissure on its head. They are generally about 1.5 meters long, females are longer than males, and females can grow to 1.96 meters. The shape of this shark is different from that of ordinary sharks, and its body is strip-shaped, a bit like an eel, also called "eel-shaped shark". The shark's mouth is different from ordinary sharks, not at the bottom, but in the front. There are 300 teeth in it, which is very sharp.

Life habits The distribution of wrinkled sharks is almost all over the world, but it is very scattered, and it is distributed in the northeastern waters of Taiwan Province Province in China. They live in the deep sea, feed on squid, bony fish and other sharks, and also eat carrion that sinks in the upper sea. Their sharp teeth make them fierce predators in the ocean, and their flexible mouths can swallow the whole prey.

In case 20 15, Australian fishermen caught a two-meter-long wrinkled shark while trawling. This is the third time that humans have captured this primitive shark, but this time it is different from the past, and it is the first time that humans have captured a live wrinkled shark. This captured wrinkled shark was finally sold by fishermen at a high price.
