Common Name: Long-finned pilot whale. Representatives from NOAA, the fishing industry, regional fishery management councils, state and federal resource management agencies, the scientific community, and conservation organizations worked together to develop the plan. Gestation lasts for 12-16 months, and females give birth to one calf every 3-6 years. Long-finned pilot whales are one of two species of pilot whale, along with short-finned pilot whales. Long-finned pilot whales have 16 to 26 peg-like teeth in each jaw, which may be an evolutionary adaptation to consuming large amounts of soft squid. Older and/or non reproductive females help care for calves in the social group. The two species of pilot whales are actually dolphins, not whales, and they are two of the largest species of dolphin, with only the Long-finned pilot whales are a species which is generally found far out to sea in the deep waters of the open ocean. An extremely friendly animal, it is also one of the most graceful and fluid swimmers when viewed underwater. Special Issue 14: 1-32. Historically, whalers benefited from pilot whales’ strong social structure and would drive and herd them together into tight groups during hunts. In the Antarctic, there are an estimated 200,000 long-finned pilot whales. Long-finned pilot whales are one of two species of pilot whale, along with short-finned pilot whales. In the Southern Hemisphere, their range extends from 19° S to 60° S, but they have been regularly sighted in the Antarctic Convergence Zone (47° to 62° south) and in the Central and South Pacific as far south as 68° south. Long-finned pilot whales are commonly seen in tight, social pods and sub-groups (usually containing more females than males) of 10 to 20 individuals, but have been reported in loose groupings of several hundred or even up to a thousand animals. Humpback whale. We also study how underwater noise affects the way pilot whales behave, eat, interact with each other, and move within their habitat.

Fun facts: They are sometimes called “pothead whales” because the shape of their head reminded early whalers of black cooking pots. To understand the health of marine mammal populations, scientists study unusual mortality events. Maximum longevity has been estimated to be around 60 years, which is plausible. Ser. Distribution and density of cetaceans, marine turtles, and seabirds in the shelf waters of the northeastern United States, June 1980-December 1983, from shipboard observations.

[35] Another study estimated a total of 780,000 animals in the North Atlantic, though this study includes both short and long-finned pilot whales as they are hard to distinguish at sea.[36]. As their name suggests, they have two very long flippers; they are crescent-shaped and have pointy tips. Then in 1986, the specific name for this species was reverted to its original form as "melas". In 2016, we issued technical guidance for assessing the effects of anthropogenic (human-caused) sound on marine mammal hearing.

The long-finned pilot whale is also covered by the Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas (ASCOBANS),[47] the Agreement on the Conservation of Cetaceans in the Black Sea, Mediterranean Sea and Contiguous Atlantic Area (ACCOBAMS),[48] the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MoU)[49] and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia (Western African Aquatic Mammals MoU). [34], Though long-finned pilot whales appear to be abundant, there have been no recent reliable estimates for the worldwide population, leading to their IUCN status of "Data Deficient." Being a toothed whale, pilot whales have a single blowhole.[10]. They are non-commercial - though people may sell their share after the catch has been divided - and organized on a community level. This species has a small, strong, low, bushy blow that is often visible. Long-finned pilot whales are economically important in the whale-watching industry of some areas of the world, especially in eastern Canada. Zwamborn, E.M.J. Black or dark grey head and back, grey-ish white anchor shaped patch on chin, and grey area on belly. Final Report, National Marine Fisheries Service, Northeast Fisheries Center, Woods Hole, MA, Contract No. [29] These repetitions are more commonly heard when whales are socializing than any other behavioral state (e.g. The initial mortality rate shows little variation among pilot whale species; however mortality rate accelerates almost twice as fast in the long-finned pilot whale as it does in killer whale and short-finned pilot whale. The effects of whale-watching on long-finned pilot whales have not been well studied. Baraff, L.S. Bryde's whale. Characterizing alloparental care in the pilot whale (Globicephala melas) population that summers off Cape Breton, Nova Scotia, Canada. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. Long-finned pilot whales, like all marine mammals, are protected under the Marine Mammal Protection Act. Long-finned pilot whales are very social in nature. This species is protected under the Marine Mammal Protection Act of 1972 as amended. 2011, Roberts et al. [8] They differ only slightly in physical size, features, colouration, and pattern.

The dorsal fin is thick and falcate in nature, and is located about a third of the way down the length of the animal. (1975). Once entangled, whales may drag and swim with attached gear for long distances, ultimately resulting in fatigue, compromised feeding ability, or severe injury, which may lead to reduced reproductive success and death.

Repeated call sequences in long-finned pilot whales: social setting, modification, and behavioral context. The two species differ slightly in size, features, coloration, and pattern. [11] However, males are bigger in size, and relative fin dimensions as well as other characteristics may still be discovered to allow for distinguishing the sex of at least certain age classes for free-ranging pilot whales. Hay, K. (1982). [23][24] Northwestern Atlantic whales are thought to dine predominately on short-finned squid.[25]. [15] However, 20 to 150 individuals are more commonly observed. Disease, Long-finned pilot whales can often be seen lobtailing and spyhopping. Although long-finned pilot whales live in groups of relatives, average within-pod relatedness is generally lower than in short-finned pilot whales and resident killer whales (Supplementary Table S1); we found that mean relatedness within pods was 0.06 (range 0.01–0.23) in comparison to 0.097 (range −0.1 to 0.38) from incomplete sampling of short finned pilot whale pods (Alves et al. Morbillivirus has affected pilot whales in the North Atlantic and certain strains of the virus may be native to specific areas. These whales have also been observed babysitting calves that are not their own, with one study showing that many of those doing the babysitting are males.[26]. (1993). Augusto, Joana F., Frasier, Timothy R., and Whitehead, Hal. You may also contact your closest NOAA Office of Law Enforcement field office during regular business hours. The historical prevalence of morbillivirus in the blood of these whales suggests that they may have increased contact with the virus. “Using our lifespan estimator and the bowhead whale genome, we estimated the maximum longevity of the bowhead whale to be 268 years. Entanglement in Fishing Gear. Targeted management actions taken to secure protections for these whales include: Minimizing the effects of noise disturbance.
