Pilot Whale
Globicephala melas · also called pilot whales, long-finned pilot whale
Surfacing together as a tightly bonded family pod, a group of pilot whales shows the deep social cohesion that defines the species, a bond so strong that healthy individuals will sometimes follow a sick or disoriented relative into the shallows rather than leave it behind.
Overview
The pilot whale, Globicephala melas, is one of the largest members of the oceanic dolphin family despite its common name, native to cool temperate and subpolar ocean waters across a broad range spanning the Atlantic, Pacific, and Southern Oceans. Its exceptionally strong social bonds, specialised deep-diving squid hunting, and tendency toward mass stranding events make it one of the more behaviourally and ecologically distinctive large dolphins found anywhere in the world’s oceans.
Loyalty that can turn tragic
The same tight family bonds that make the pilot whale such a socially cohesive species can also prove fatal, with entire pods sometimes stranding together on beaches as healthy members refuse to abandon a struggling relative.
Status
Least Concern overall but decreasing in parts of its range, with declines linked to bycatch, historical hunting in some regions, and periodic mass stranding events.
Pilot Whale: common questions
Is the pilot whale actually a whale?
Not in the strictest taxonomic sense; despite its common name, this species is actually one of the largest members of the oceanic dolphin family, with the name whale reflecting its considerable size and appearance rather than a genuine difference in classification from smaller dolphin species.
Why do pilot whales sometimes strand in large groups?
This species forms exceptionally tight, long-lasting social bonds within stable family pods, and researchers believe mass stranding events occur partly because healthy individuals follow sick, injured, or disoriented pod members into shallow water rather than abandoning them, a consequence of the species' strong social cohesion.
What does the pilot whale eat?
This species feeds heavily on squid, along with some fish, hunted during deep dives in open ocean water, often diving deeper and longer than many smaller dolphin species in pursuit of this specialised prey.
How can you recognise a pilot whale?
Look for a distinctively rounded, bulbous forehead without a pronounced beak, a dark overall colouration, and a considerably larger body size than most other dolphin species, features that together give the pilot whale a silhouette quite different from more streamlined dolphins.
