Not long ago, several scientists accidentally caught a frilled shark about 1.5 meters long off the coast of Algarve, Portugal. 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 frilled shark is quite different from the general shark in appearance, but it is somewhat similar to the eel.

Morphological characteristics The wrinkled gill shark is named after its head has gill slits with folds. They are generally about 1.5 meters long, and 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, which is somewhat similar to eel, also known as "eel-like shark". The shark's mouth is also different from that of ordinary sharks, not at the bottom, but in the front, with 300 teeth inside, which is very sharp.

Life habits The distribution of frilled sharks is almost all over the world, but it is very scattered, and it is found in the northeastern waters of Taiwan Province in China. They live in the deep sea, feeding on squid, bony fish and other sharks, and also eating carrion that sinks from the upper layer of seawater. Their sharp teeth make them fierce predators in the ocean, and a flexible mouth can swallow the whole prey.

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