The humpback is one of the great whales – a baleen whale, it’s of the larger rorqual species, with adults ranging from12-16 metres (40-50 ft) and weighing around 36,000 kilograms (79,000 lb). The humpback whale is the owner of a distinctive body shape, with extremely long pectoral fins and a head with with bristly nobbles. Humpbacks are acrobatic whales, and can be see breaching and slapping the water. Males produce a complex whale song, which lasts for 10 to 20 minutes and is repeated for hours at a time. The purpose of the song is not yet clear, although it appears to have a role in mating.
