On 3 May 2022, in a remote protuberance off the coast of Papua New Guinea, scientists encountered something amazing: a walking shark. Using fins to travel, a tiny black and brown fish swam into a crawl puddle that barely contained water, moving like a clumsy sea lion, dragging the body along the shore.
This creature turned out to be an e-fly shark, and it's unique among other kinds of land walkers. Forrest Galante, a conservationist and biologist, has recently shared rare human resources of this unusual species in a special issue of Discovery Channel "The Week of Sharks".
"This is the first time in history that one of the papois species was filmed while walking," said Galante in the issue. "It's incredible."
Scientists believe that epolet sharks, a species all over the southern coast of New Guinea and the northern coast of Australia, have developed the ability to walk because it has helped them to obtain food in conditions where other sharks could not survive.
