Long-finned pilot whale

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. 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 Latin globus ("globe") and Greek kephale ("head"). The specific name "melas" is Greek for "black". This species has also earned the nickname of "pothead whale" in some places because the shape of its head reminded early whalers of black cooking pots. This species was first classified in 1809 by Thomas Stewart Traill and given the name "Delphinus melas". However, this scientific name was changed later to "Globicephala melaena". Then in 1986, the specific name for this species was reverted to its original form as "melas". There is sexual dimorphism in the species. Females grow to a maximum length of up to , and a maximum weight of up to . Males are significantly larger at up to in length, and weigh up to . This makes the long-finned pilot whale the second largest member of the dolphin family, behind the killer whale (Orcinus orca). Despite its common name, the long-finned pilot whale is actually a large species of dolphin. The same is true of orcas and several other small whales. It has a bulbous forehead and is black or dark grey in colour with light-grey or white markings on the throat and belly regions. This light grey patch found on the throat of pilot whales forms the shape of an anchor. Some individuals have other distinct markings such as a light coloured area behind dorsal fin, known as a saddle patch, as well as an upwards sweeping stripe just behind the eye. The dorsal fin is thick and falcate in nature, and is located about a third of the way down the length of the animal. The common name of this species is a reference to the pilot whale's long, sickle-shaped pectoral flippers that are 18 to 27 percent of its total body length.

Whale meat

Whale meat, broadly speaking, may include all cetaceans (whales, dolphins, porpoises) and all parts of the animal: muscle (meat), organs (offal), skin (muktuk), and fat (blubber). There is relatively little demand for whale meat, compared to farmed livestock. Commercial whaling, which has faced opposition for decades, continues today in very few countries (mainly Iceland, Japan and Norway), despite whale meat being eaten across Western Europe and colonial America previously.

False killer whale

The false killer whale (Pseudorca crassidens) is a species of oceanic dolphin that is the only extant representative of the genus Pseudorca. It is found in oceans worldwide but mainly in tropical regions. It was first described in 1846 as a species of porpoise based on a skull, which was revised when the first carcasses were observed in 1861. The name "false killer whale" comes from having a skull similar to the orca (Orcinus orca), or killer whale. The false killer whale reaches a maximum length of , though size can vary around the world.

Atlantic white-sided dolphin

The Atlantic white-sided dolphin (Lagenorhynchus acutus) is a distinctively coloured dolphin found in the cool to temperate waters of the North Atlantic Ocean. The dolphin is slightly larger than most other oceanic dolphins. It is just over a meter in length at birth, growing to about (males) and (females) at maturity. It weighs 180–230 kg (400- 510 lb) once fully-grown. Females reach sexual maturity at between 6 and 12 years, and males between 7 and 11 years.
