Long-finned Pilot Whale (Globicephala melas) lives in open ocean waters across North Atlantic Ocean. It feeds on squid and fish. Its conservation status is Least Concern.
Fascinating facts about the Long-finned Pilot Whale
- Long-finned pilot whales can grow to a length of 7.6 m (25 ft) and weigh up to 4,500 kg (9,900 lb), making them the second-largest dolphin after the orca. Females reach a maximum length of 6 m (20 ft) and weigh up to 2,500 kg (5,500 lb). Their pectoral flippers stretch 18-27 % of that total length, giving the species its name. underscoring their role as apex marine predators.
- Mass strandings are a hallmark of this species; the largest recorded event involved about 1,000 individuals on New Zealand's Chatham Islands in 1918. More recent events, such as the 600-plus whales stranded at Farewell Spit in 2017, show that these gatherings can still reach staggering numbers. The phenomenon is linked to their tight matrilineal bonds, when one whale beaches, the rest often follow, highlighting how social cohesion can become a liability in hazardous situations.
- North Atlantic long-finned pilot whales have become a sentinel species for oceanic pollution: tissue analyses from 1986-2023 show a 60 % drop in legacy PFAS concentrations, yet a newer replacement, C4 FASA, has risen about 7 % per year since 2001. This dual trend illustrates both the success of regulatory phase-outs and the ongoing problem of "regrettable substitution," where banned chemicals are swapped for similarly persistent alternatives that still threaten top predators.
- These whales travel across both hemispheres, preferring cool waters between 13 °C and 30 °C and diving to depths of 1,800 m (5,900 ft). Their range stretches from the North Atlantic, off Greenland, Iceland, the Barents Sea, and down to the Mediterranean, to the Southern Ocean as far as 68° S, even near sea ice.
- Almost twice as many neocortical neurons as a human, the highest count recorded in any mammal. Their complex vocal repertoire, which includes rapid clicks for echolocation and repeated call sequences that intensify during socializing.
