Scientists believe there are about one million long-finned and 200,000 short-finned pilot whales worldwide. The long-finned pilot whale is widely distributed in deep pelagic waters from sub-polar to warm temperate regions. Scientists say the reason is often unknown but they have a range of theories, including whales being lured by fish to shore and becoming disorientated. Sadly, perhaps the thing that pilot whales are most famous for is their tendency to mass strand on beaches. Adult pilot whales are black or dark grey and have a lighter grey saddle patch on the back behind the dorsal fin and an anchor-shaped patch on the underside. Long-finned pilot whales are active predators that eat mostly squid, including relatively large-bodied species.

"Geographically it's quite a challenging area. Possible causes are navigation mistakes when following prey or travelling (perhaps due to irregularities in the magnetic field), or possible parasitic infections resulting in neurological disorders, or perhaps the whole pod simply sticks together to support an ill whale. Please read our privacy policy for information on how we handle your data. The total worldwide population size may number several hundred thousand whales.

Once the whales are "re-floated", they are guided back into deeper waters. Pilot whales can grow up to 7m (22 ft) long and weigh up to three tonnes. It is likely that the bonds of social cohesion cause these refloated whales to return to shore if others of their group remain in distress.  Refloating stranded whales has to be carefully managed to ensure whales leave the beach together, or in large enough groups to offset the impulse to return.

General information repSubAnnexVSpecies3. Long-finned pilot whales live throughout the cold and temperate waters of the southern hemisphere and in the North Atlantic Ocean; they have a wide distribution around the globe. Fisheries, particularly those for squid, may affect prey availability for pilot whales. Short-finned pilot whales are a bit smaller and their flippers are not quite as long (they are a sixth of the body length rather than a fifth). There are usually more females than males as their pods are built on units of mothers and their offspring. Other living relatives of the pilot whales are the melon-headed whale, the pygmy killer whale, the false killer whale, and Risso's dolphin.

According to the IUCN Red List, the total population size of the LOng-finned pilot whale is unknown. Huge multi-pod get-togethers of hundreds or even a thousand pilot whales give ample opportunity for males to mix and breed with females from other families. The aim here was to estimate demographic parameters of long‐finned pilot whale (Globicephala melas) from the Strait of Gibraltar by fitting mark‐recapture models to photo‐identification data of primary and secondary marked individuals. The total worldwide population size may number several hundred thousand whales. Mainly squids and octopus; these cephalopods are definitely their favoured food.  They do sometimes eat fish such as mackerel, hake, herring and cod. Long-finned pilot whales were historically targeted by whalers and the population in the eastern North Atlantic was estimated at over 700,000 animals in the late 1980’s.

Long-finned pilot whales are also often observed by whale watching vessels in the Gulf of Maine USA, while short-finned pilot whales can be observed in Hawaii. In the St. Lawrence, this population is estimated at 1,600 individuals (as per aerial surveys of the Gulf conducted in 1995).

"Some long-finned pilot whale calls were found to be remarkably similar to those of the same species in the Northern Hemisphere, which is surprising as non-equatorial aquatic mammals such as these are not expected to cross the equator for large-scale migrations, meaning the last contact the two hemispheres' populations could have had would have been more than 10,000 years ago.
