Once the stingray moved in, the difference between the real crabs and the robot became impossible to miss. The living crabs stayed tucked into their defensive pile, layered over one another in a way that made them much harder to reach. But the robot crab had no such protection. It remained exposed, separated from the group, and directly in the path of the predator. And almost immediately, the stingray went for it.
The footage showed the ray targeting the robot crab, nudging it, pushing at it, and eventually flipping it onto its back. For a moment, it looked like that was it. The robot had essentially been singled out and abandoned while the real crabs protected themselves. And honestly, that would’ve made perfect sense. Because why wouldn’t they? To them, this thing wasn’t really one of them. It was just some strange crab-shaped object that had wandered too close at the wrong time. But then something happened that changed the entire feel of the experiment.
Because the pile of crabs didn’t stay still. As the robot lay overturned and vulnerable, the others seemed to notice what was happening. And then, incredibly, they started moving toward it.
