A set of precious footage captures the epaulette sharks, also known as semi-green crabs, walking on a Papua New Guinea beach. The video was filmed as part of The Discovery Channel's annual Shark Week and is titled "Walking Shark Island."
Sharks swimming in the water is not enough to worry, now there are sharks can walk on land, just ask you are afraid? This type of shark is found in southern Papua New Guinea and northern Australia, and scientists believe they have evolved amazing walking abilities that can help them find food in places where other sharks can't reach.
The epaulette shark is a very scary fish that can drag itself through the ground with its fins like a sea lion. Fortunately, this particular shark is only about 90 centimeters long and poses no real threat to humans.
Conservationist and biologist Forrest Garrant described the scene, filmed in May, as "incredible." "This is the first time in history that papua epaulette sharks have been recorded walking on shore," he said. ”
Epaulette sharks can cross land for more than 30 meters and can stay on shore for an hour with just one breath. This evolutionary result helps them survive in tidal pools with low oxygen levels as well. They look for their favorite crabs, worms and other invertebrates in shallow reefs.
Gavinnelle, director of the Florida Shark Research Program at the Florida Museum of Natural History, told the media: "All the features are designed to allow a species to survive better and maintain a safe environment so that they can get food." Epaulette sharks learn to climb up the reef and then swoop into the next tide pool. ”
The epaulette shark's back is covered with unique black dots that vary so much that no two individuals look similar. Some scientists, including Neller, believe they can even change their color patterns at any time, although this theory has not been confirmed.
