Both males and females remain within their matriarchal pod for their entire lives. It is speculated that the mating ritual of pilot whales can be quite aggressive, given the evidence of biting and head butting on both males and females.
Short-finned pilot whales are one of the few cetaceans that experience menopause. Pilot whales continue to experience hunting pressures that easily exploit their social behaviour. Hunted for their meat, bones, and oil, inshore fishermen from Newfoundland hunted pilot whales for decades reaching a maximum of 10, whales harvested in alone. In the North Pacific Ocean, long-finned pilot whales are regionally extinct, likely a result of exploitation.
Despite heavy hunting, pilot whales were never exploited to the same extent as baleen whales like humpback, bowhead or fin whales. There is no fishery targeting pilot whales in Canada today, but they are caught as bycatch in fishing gear such as gillnets, trawls , driftnets and purse seines.

There are an estimated one million long-finned and , short-finned whales worldwide. Otherwise, there is very little information on their global abundance or population trends. Below are the conservation statuses of each population:. Species at Risk Public Registry - long-finned pilot whale. Pilot whales are actually large dolphins ; they are the second largest member of the oceanic dolphin family second only to orcas in size.
Pilot whales are extraordinarily social; their strong bonds with one another motivate them to stick together through thick and thin, even when that means putting themselves at risk. Other names: Atlantic pilot whale, Pothead whale, Caa'ing whale, Blackfish. As their name suggests, they have two very long flippers; they are crescent-shaped and have pointy tips.
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. Pilot whale babies are paler coloured. Pilot whales are long, robust whales and have a thick-set, curved sometimes hooked , and very prominent dorsal fin.
The head is bulbous with no beak. Male pilot whales are larger than females, and they have a more bulbous forehead and chunkier dorsal fin.
Pilot whales have a very sociable and inquisitive nature. They are long-lived and live together in multi-generational, tight-knit, stable pods. There are usually more females than males as their pods are built on units of mothers and their offspring.
Baby pilots grow up within the safety of the pod they are born into and remain within the same pod for life. Older females or those who are not giving birth themselves, help mothers in the pod care for their babies.
Pilot whales are strongly bonded to each other and do everything together; resting, hunting, socialising, playing and travelling as a unified pod. The most important thing in their lives is each other and they are incredibly loyal. There can be anything from 10 to 20 all the way up to a hundred pilot whales living together in a pod. 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.
Pilot whales are often active at the surface; they may spyhop poke their heads out of the water , or lobtail lift their flukes out of the water and splash them down. They are also regularly seen resting logging in unison, close to each other at the surface. Sometimes they will approach vessels moving at slow speeds and will often allow slow-moving whale-watch boats to approach them.
Pilot whales can dive to depths of over m for 10 to 16 minutes at a time to hunt. They mostly feed at night in deep water using echolocation to find prey. Mainly squids and octopus; these cephalopods are definitely their favoured food. They do sometimes eat fish such as mackerel, hake, herring and cod.
Their squid eating lifestyle is evident when looking inside their mouths as they have far fewer teeth than dolphins that prefer fish.
They eat about 70 pounds of food daily, which is actually a small amount compared to other types of whales their size. Long-finned pilot whales usually travel in large matriarchal pods containing hundreds of cetaceans. They are highly social animals, and researchers say that both males and females remain in their mother's pod.
Short-finned pilot whales are one of the few mammal species in which females go through menopause. Pilot whales have one of the longest birth intervals of all cetaceans, calving once every three to five years. Pilot whales are known for stranding themselves on beaches. The pilot whale received its name due to the belief that the pod follows a single leader.
