Male fiddler crabs have one oversized claw, which they use to attract females by standing outside their burrow and waving.

In the new study, a robot crab—nicknamed Wavy Dave—waved its claw on a mudflat teeming with male fiddler crabs. The paper, ...

Between May and July 2022, Wilde and his team created “Wavy Dave,” an artificial fiddler crab with a robotic claw that could wave back and forth. It was placed in the Ria Formosa Natural Park in the ...
