Sharks’ hunting paths may not be driven by math

Sharks, penguins and other marine hunters have been shown to use math to find food. However, new simulations suggest that the animals appear to move in a strict mathematical pattern called a Lévy walk because they hit rough water. The movement patterns could therefore be a “fortuitous accident” rather than a result of natural selection, Rothamsted Research scientist Andrew Reynolds writes September 17 in the Proceedings of the Royal Society A.
