Beaked whales are among the cetaceans most frequently associated with mass strandings linked to intense sonar exposure.

Baird’s beaked whales depend on precise echolocation clicks to hunt in total darkness, but intense anthropogenic noise such as naval sonar can interfere with their acoustic navigation systems.

In an environment where survival depends on sound, powerful sonar pulses can mask prey echoes or trigger stress responses during deep dives, potentially disrupting feeding behavior thousands of meters below the surface.

Because these whales inhabit offshore canyons where military and industrial activity may occur, their extreme specialization for acoustic hunting makes them uniquely vulnerable, highlighting the fragile balance between technological expansion and deep-ocean life.
