Masters of Hunting: How Seal Whiskers Help Them Outsmart Fish 0 56

When fish make sharp jerks, they create vortex rings of different sizes that can confuse predators. However, seals learn to distinguish which of the two vortices is larger, even with a difference of just 1.8 cm. This skill helps them predict the trajectory of their prey and increases their chances of successful hunting.

Experiments with a seal named Phil confirmed the high sensitivity of whiskers to the slightest eddies. This ability gives seals an advantage in murky water and low visibility, making hunting more effective.

Whiskers allow them to detect even micro-vibrations in the water caused by fish breathing, significantly expanding their prey detection capabilities. These discoveries may inspire engineers to create new underwater sensors.
