Overview

Pilot whales (genus Globicephala) are large, dark, robust members of the dolphin family — despite the name “whale.” There are two species, the long-finned and short-finned pilot whale, both recognised by a bulbous, rounded forehead (melon) and a strongly social way of life. The animal shown here is the long-finned pilot whale (Globicephala melas).

Pilot whales are deep divers that hunt squid far below the surface, and they are known for the strength of their social bonds, which keep groups tightly together.

Conservation note: pilot whales are widespread, but their strong group cohesion makes them vulnerable to mass strandings and to drive hunts in a few regions. Verify current status at iucnredlist.org and NOAA Fisheries.

Habitat & Range

Pilot whales range widely through deep temperate and tropical waters, mostly offshore over the continental slope and open ocean. The long-finned species favours cooler waters, while the short-finned species occupies warmer seas; their ranges overlap in some areas.

Diet

Pilot whales feed mainly on squid, along with some fish. They are capable deep divers, descending hundreds of metres to reach prey, sometimes in fast “sprint” dives. Groups often forage together at depth.

Behavior

Pilot whales are exceptionally social, living in stable groups built around long-term bonds; in some populations individuals stay in their natal group for life. They communicate with whistles and calls and use echolocation to hunt in the dark depths. Their powerful group cohesion — usually a strength — is also thought to contribute to mass strandings, when a whole group may follow others into trouble.

Human Interaction & Conservation

The main human-related concerns for pilot whales are drive hunts in a few locations, accidental capture in fishing gear, pollution, and noise. Their tendency to mass-strand also brings them into contact with rescue efforts. For current status and regional context, consult NOAA Fisheries and the IUCN Red List.

Intelligence & Social Complexity

Pilot whales are highly intelligent and among the most socially bonded of all cetaceans. They live in stable, long-lasting groups, coordinate deep cooperative dives, and communicate with a complex range of calls; like orcas, some populations show long post-reproductive survival in females, suggesting older individuals carry valuable knowledge for the group. This intense sociality — central to their lives — is also why disturbances can affect a whole group at once.

Frequently Asked Questions — Pilot Whale

Is a pilot whale really a dolphin?
Yes. Despite the name, pilot whales are large members of the dolphin family (Delphinidae). Several big delphinids — including the orca and pilot whales — carry the name "whale," but they are dolphins, which are themselves toothed whales.
Why do pilot whales mass-strand?
Pilot whales have extremely strong social bonds and tend to stay together. While usually an advantage, this cohesion is thought to contribute to mass strandings: if some individuals end up in danger — through illness, navigation errors, or difficult coastlines — others may follow. The exact causes of any given stranding are complex and studied case by case.
What do pilot whales eat?
Mainly squid, plus some fish. Pilot whales are capable deep divers, descending hundreds of metres to hunt, sometimes in rapid dives, and groups often forage together.
How intelligent are pilot whales?
Very. As large-brained members of the dolphin family, pilot whales show advanced cognition and exceptional social complexity, with stable lifelong groups, cooperative deep-diving, and rich communication. Some populations also show long post-reproductive female lifespans, a trait linked to knowledgeable group elders.
