Short-finned Pilot Whale
These highly social cetaceans dive to impressive depths searching for squid. They produce clicks between 10-80 kHz that function effectively in the darkness of deep water. Short-finned pilot whales regularly descend to 1,000 meters below the surface. They use social clicks to maintain contact with pod members during dives. Their tight family structure depends on constant acoustic connection. Their clicks serve dual purposes: finding prey and keeping the group together during extended foraging trips into the lightless deep ocean.
