How seals’ whiskers make them master underwater hunters

For two years, a harbor seal named Filou helped scientists explore how seals use their whiskers to hunt fish. These whiskers, or sensory hairs, allow seals to detect water movements left by fish, similar to how an airplane leaves a visible trail in the sky. This ability helps seals track and catch fish, even when the fish try to escape using evasive maneuvers. In experiments, Filou demonstrated that seals can sense and interpret these underwater trails, potentially outsmarting fish like the rainbow trout, which use clever swimming techniques to avoid predators. This research highlights the remarkable hunting skills of harbor seals and their reliance on whiskers to navigate and survive in their aquatic environment. QUESTION: How might understanding the hunting techniques of harbor seals influence the way we approach marine conservation efforts?
