Researchers used a robotic crab to study male fiddler crabs' mating competition behaviors.
Scientists used a robot crab named "Wavy Dave" to study how male fiddler crabs compete during mating season.
The robot, designed to mimic the large claw movements of male crabs, helped researchers understand the crabs' behavior in rivalry situations.
The study found that male crabs adjust their claw-waving based on the size of the robot's claw and don't necessarily increase their own waving speed, suggesting they may be more cautious when they perceive larger rivals.
