The Shark That Casually Began To Stroll On Land
If you’re scared of sharks, you probably aren’t keen on knowing that there are at least nine species of shark that can use their fins to move in shallow water, and even briefly on land.
That said, even though “walking” sharks have been documented previously, the recent footage of a epaulette shark moving from the water onto land during Discovery’s Shark Week is pretty sensational.
The video was shot on Papua New Guinea, during Island of the Walking Sharks, and though the teaser claims the footage is “the first time in history one of the Papuan species has been documented walking,” a Twitter thread is pushing back.
One person, Kevin Connor, noted that the behavior is well-known and is currently being studied by several research institutions in Indonesia and beyond.
woof. classic parachute 'science' from shark week and an EXTREMELY doubtful claim that "This is the first time in history one of the Papuan species of epaulettes has been documented walking". Don't get me wrong, walking sharks are cool AF, but broski here is not the 1st to notice pic.twitter.com/iUeHPlfHc3

Epaulette sharks are small and honestly kind of cute; some people even keep them as pets. And even if the video isn’t technically new information, it’s clear and there’s a good chance a majority of laypeople haven’t been aware sharks can “walk” on land until now.
Sharks that can “walk” typically do so on the ocean bottom, where laying flat allows them to hunt for prey under rocks and corals. All of the known sharks that exhibit this behavior reside off the coasts of New Guinea, Australia, and Indonesia, but scientists believe there are almost certainly more species out there able to do the same.

We don’t know for sure how many can come out of the water to display the behavior on land, but marine biologists believe they probably evolved from a bony fish, not a shark at all.
Evolution is definitely at play, here, but more study is needed to understand why some of these sharks now walk on land as well as on the bottom of the ocean.
