Pilot Whale (Long & Short-finned)

Highly social, intelligent & deep divers.

Pilot whales, comprising long-finned and short-finned species, exhibit profound familial ties within their large, structured groups, sometimes numbering in the hundreds. Their sophisticated social dynamics are underscored by their vocal communication skills, essential for navigating and hunting in deep waters. These cetaceans are adept at deep-sea foraging, primarily hunting squid, using echolocation – a testament to their complex social and hunting strategies.

Despite their close genetic and behavioral similarities, differentiating between the two species in their natural habitat poses a significant challenge due to their shared physical characteristics. Their societal structures are complex, with groups often led by a matriarch, illustrating their intricate social hierarchies and bonds that can span lifetimes, highlighting their unique place in the marine ecosystem.

Behavior & Feeding

Socializing +

Pilot whales demonstrate vital social behaviors for their survival and success in reproduction, engaging in both acoustic and non-acoustic interactions. They communicate through complex vocalizations, including whistles for pod cohesion, echolocation clicks for navigation and locating prey in deep waters, and burst-pulsed sounds for varied social functions. These whales also exhibit distinctive dialects and adjust their vocalizations based on their activity, underlining the role of sounds in their social lives. Additionally, body behaviors like breaching and spyhopping vary between species, contributing to their social interactions.

Resting +

Surface activities of pilot whales, especially post-foraging at sunrise, primarily consist of resting. They are often observed resting at the surface, indicating a significant portion of daylight hours is dedicated to recuperation.

Foraging & Diet +

Pilot whales are adept nocturnal hunters, specializing in deep-sea dives along continental slopes to catch prey. Their diet mainly consists of squid, though they may also consume octopus and deep-water fish. Utilizing echolocation, they hunt with precision, employing tactics like high-speed chases facilitated by rapid click “buzzes” for efficient predation. The technique known as “ram-and-suction” is used to capture their prey, showcasing their adaptability and skill in feeding strategies.

Distribution & Movements

Long-finned pilot whales predominantly inhabit the cooler waters of both the northern and southern hemispheres, favoring the temperate and subpolar regions. These environments provide the necessary conditions for their feeding habits and social behaviors. On the other hand, short-finned pilot whales are more commonly found in warmer, tropical, and subtropical waters. This distribution pattern highlights the species’ adaptability to a range of oceanic conditions, from the cooler, nutrient-rich temperate zones to the warmer, biodiverse tropical seas. Despite their overlapping ranges in some areas, the distinct thermal preferences of each species facilitate their adaptation to specific ecological niches, reflecting the remarkable diversity and adaptability of cetaceans to the world’s oceans.

Reproduction & Life History

Sexual Maturity

8-17 years
Females at 8-9 years of age, males at 13-17 years.
However, males do not mate successfully until several years later.

Gestation

14-16 months

Number of calves

4-5 calves in a lifetime
Calving occurs every 3-5 years, with older females having up to eight years between births. Calves are born year-round, with peaks in spring and autumn in the southern hemisphere and autumn and winter in most northern hemisphere populations.

Suckling period

2-3 years or longer
Post-reproductive females may continue to suckle their last calf for up to 7 years (females) or 15 years (males), possibly to give the offspring a reproductive edge. Calves can eat solid food from about six months of age.

Lifespan

35-60 years
Females can live for at least 60 years, while males have a lifespan of 35-45 years.
The oldest recorded ages are 46 years for a male and 63 years for a female. Older, non-breeding females may provide babysitting services and/or act as keepers of ecological wisdom.

Mating strategy

Presumed polygynandrous
Both males and females have multiple mating partners.
Males move between groups to mate, highlighting a complex social structure and reproductive strategy within Pilot Whale populations.
