Half a billion years after an arthropod with long triple claws roamed the shallow Cambrian seas, scientists have named it after Hollywood movie actor, Johnny Depp: Kooteninchela deppi. Depp, known for his versatility as an actor, played Edward Scissorhands—an artificial man with long scissors for hands—in a popular 1990 film.

The species was discovered in Stanley Glacier in Canada’s Kootenay National Park. Legg believes that Kooteninchela deppi was either a predator or scavenger 500 million years ago, likely using its long scissors-like claws to skewer prey or probe the sea bottom for food. Although it sounds monstrous, Kooteninchela deppi was quite tiny: about 4 centimeters long.Kooteninchela deppi belongs to an animal group known as megacheirans or ‘great-appendage’ arthropods. These are early relatives to modern arthropods, which include everything from insects to arachnids to crustaceans.

“Just imagine it: the prawns covered in mayonnaise in your sandwich, the spider climbing up your wall and even the fly that has been banging into your window and annoyingly flying into your face are all descendants of Kooteninchela deppi,” Legg says. “Current estimates indicate that there are more than one million known insects and potentially 10 million more yet to be categorized, which potentially means that Kooteninchela Deppi has a huge family tree.”
