Genus and size
Pilot whales belong to the genus Globicephala and are among the largest oceanic dolphins, second in size only to the orca.
Species Guide
What to know about pilot whales
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
Pilot whales are cetaceans of the genus Globicephala with two extant species: the long-finned pilot whale (G. melas) and the short-finned pilot whale (G. macrorhynchus). They are among the largest oceanic dolphins, exceeded in size only by the orca, and are also referred to as blackfish. The two species are not readily distinguishable at sea; skull analysis is the most reliable method for species-level identification. Long-finned pilot whales inhabit colder waters, while short-finned pilot whales occur in tropical and subtropical waters. Pilot whales feed primarily on squid and will also hunt large demersal fish such as cod and turbot. They are highly social, often remaining with their birth pod for life. Short-finned pilot whale females undergo menopause and postreproductive females continue to contribute to their pods. Pilot whales are known to strand on beaches, and some research links strandings to damage to their inner ear from underwater noise pollution. The conservation status of both long-finned and short-finned pilot whales is assessed as Least Concern.
Both the long-finned and short-finned pilot whales have been assessed as Least Concern.
Highly social; individuals may remain with their birth pod throughout their lifetime.
Identification
How to identify pilot whales
The visual markers divers can use underwater, plus the species most likely to cause confusion.
Key identification markers
Two species with different ranges
There are long-finned and short-finned species; long-finned occur in colder waters, short-finned in tropical and subtropical waters.
Difficult to distinguish at sea
The two species are not readily distinguishable at sea; skull analysis is the most reliable identification method.
Common lookalikes
Orca (killer whale)
Orcas are larger than pilot whales; pilot whales are among the largest dolphins but are exceeded in size by orcas.
Range and Movement
How pilot whales move through the world
The broad range, seasonal movement, or migratory behavior that shapes where divers encounter this species.
Highly social; individuals may remain with their birth pod throughout their lifetime.
Diet
What pilot whales tend to eat
Useful feeding context that often explains habitat, movement, and encounter style.
Primarily squid, and also large demersal fish such as cod and turbot.
Conservation
What is happening with Pilot Whales
Status, pressure, and protection context grounded in cited sources rather than filler.
Both the long-finned and short-finned pilot whales have been assessed as Least Concern.
Main threats
Noise pollution and inner ear damage
Underwater noise from sources such as cargo ships or military exercises can damage pilot whales' inner ear (their principal navigational sonar), which has been suggested as a factor in beach strandings.
Stranding events
Pilot whales are notable for mass strandings on beaches; the underlying reasons are not fully understood and may be linked to sensory impairment.
Responsible Encounters
How to dive with pilot whales
Conservation-minded guidance for divers who want the encounter without adding pressure.
Give pilot whale space, avoid blocking the animal's path, and follow local site and operator rules for wildlife interactions with whales.
Field Notes
Interesting things worth knowing
Useful species context that makes the encounter more meaningful once you are underwater.
Field notes
Postreproductive females
Short-finned pilot whale females undergo menopause and postreproductive females continue to play a role in their pods.
Known for strandings
Pilot whales are notorious for stranding themselves on beaches, a phenomenon not fully understood.
