The short-finned pilot whale was described, from skeletal materials only, by John Edward Gray in He presumed from the skeleton that the whale had a large beak. The long-finned pilot whale was first classified by Thomas Stewart Traill in as Delphinus melas.

[David E Sergeant; Fisheries Research Board of Canada,]. The pilot whale is a gregarious species often found in groups ofin which there are often small families of females and their calves.

Although males are found in these groups as well, they are not necessarily fathers of the calves. Pilot whales are often associated with mass strandings of several hundred animals. Aspects of the biology of Pilot whales (Globicephala melaena) in recent mass strandings on the British coast A.

MARTIN Sea Mammal Research Unit, Natural Environment Research Council, c/o British Antarctic Survey, High Cross, Madingley Road, Cambridge CB3 OETCited by: The long-finned pilot whale (Globicephala melas) is a large species of oceanic dolphin.

It shares the genus Globicephala with the short-finned pilot whale (Globicephala macrorhynchus). Long-finned pilot whales are known as such because of their unusually long pectoral fins. Taxonomy and naming Etymology.

Pilot whales get their name from the original belief that there was a "pilot" or lead individual in their groups. The name for the genus, "Globicephala" is derived from a combination of the Latin words globus ("globe") and kephale ("head").The specific name "melas" is Greek for "black".This species has also earned the nickname of "pothead whale" in some places.

Despite their name, pilot whales are not whales at all—they are large dolphins. The common name "pilot whale" comes from an early belief that a pod of whales was led by a pilot or leader.

Found in oceans worldwide, the two species are the long-finned pilot whale (Globicephala melas) and short-finned pilot whale (G. macrorhynchus). Pilot whale, (genus Globicephala), also called blackfish or pothead whale, either of two species of small, slender toothed whales of the dolphin family Delphinidae.

Among marine mammals, pilot whales (Globicephala melas) are characterized by high levels of tissular cadmium (Cd).In this species, squids are used as a major food item, inducing an important Cd intake.

In a significant fraction of the mammal population sampled in the vicinity of the Faroe Islands, blood and urine Cd concentrations are higher than minimum adverse-effect levels established. 55 Globicephala melaena were autopsied in Newfoundland and the helminths recovered listed.

There are brief notes on pathogenicity. The whales become infected after weaning, when they take to a diet of squid and cod. Orthosplanchnus arcticus and Diphyllobothrium sp. are first records from G. melaena. Blood Studies on the North Atlantic Pilot (Pothead) Whale, Globicephala melaena (Traill, ).

melas).It is part of the oceanic dolphin family (Delphinidae). Long-finned pilot whales (Globicephala melas) are rare visitors to the southern North Sea, but recently two individual strandings occurred on the Dutch coast.

Both animals shared the same, unusual cause of death: asphyxiation from a common sole (Solea solea) stuck in their nasal cavity. This is a rare cause of death in cetaceans. datasets have provided data to the NBN Atlas for this species.

Pilot whales are two cetacean species (Globicephala melasand G. macrorhynchus) whose distributions are correlated with water temperature and partially overlap in some areas like the North Atlantic Ocean.

In the context of global warming, distribution range shifts are expected to occur in species affected by temperature. D.E.

The long-finned pilot whale is widely distributed in the temperate, sub-polar waters of the world (with the exception of the North Pacific) and two subspecies are separated from each other by tropical waters: G.

edwardii in the south and G. melas in the north. Long-finned pilot whales prefer areas of high relief, submerged banks, and the edge of the continental shelf. The short-finned pilot whale was described, from skeletal materials only, by John Edward Gray in He presumed from the skeleton that the whale had a large beak.

The long-finned pilot whale was first classified by Thomas Stewart Traill in as Delphinus melas. [3] It's scientific name was eventually changed to Globicephalathe specific name of the long-finned pilot.
