When it comes to sharks, it’s assumed that many people will first think of the terrible image in the Great White Shark movie. But scientists have recently discovered four new types of sharks that, not only do not pose any threat to humans, but rather give the impression of a unique way of moving. In the tropical waters of the Indo-Australian Islands between Indonesia and Australia, the team discovered four new shark species. Sharks that walk on the seabed with their feet are very rare in shark populations.
“These new sharks, with an average body length of less than 1 meter (3.2 feet), are not a threat to humans,” said Dr Christine Dudgeon of the University of Queensland in Australia. But their ability to withstand low oxygen and the ability to walk on fins gives them a significant advantage in preying on small crustaceans and molluscs. “
Although humans have previously found walkable sharks, the team’s discovery of the four species suggests that nine species of shark can walk. After DNA analysis, the team believes that long ago, sharks separated from their siblings and became a new species.
“The data suggest that the new species evolved after sharks left their original populations, and they were genetically isolated in new areas and developed into new species,” Dudgeon said. They may have moved by swimming or walking on their fins, but they may have ‘hitchhiked’ west two million years ago across the coral reefs at the top of New Guinea. We believe there are many more walking shark species waiting to be discovered. “
