"You get a lot of reef sharks and shovel-nosed rays, things like that, and hammerheads," Daryl Roberson, who runs a business on the beach, told Australian broadcaster ABC.

It also marks out the Mohave shovel-nosed snake as rather different from other species, which the team has observed in a nearby zoo adopting much more irregular and complicated shapes.

"This is the Mohave shovel-nosed snake," says Perrin Schiebel as she hands me a 40cm reptile.

Ms Schiebel has "tens of thousands of frames" of high-speed video showing the shovel-nosed snake navigating the tank, both with and without obstacles.
