They are about 1.2 metres (3 ft 11 in) at birth, growing to about 3.5 metres (11 ft) at … There is a light coloured marked, C-shaped, usually referred to as a “false gill”, along the side of the head between the eye and the pectoral flipper. The pygmy sperm whale was first described by naturalist Henri Marie Ducrotay de Blainville in 1838. At sea it is often difficult to distinguish them from the Dwarf Sperm Whale, which only differs in size and shape of the dorsal fin. The mating and calving season lasts about 9 months and peaks in March through August in the Northern Hemisphere.  Dives have been estimated to last an average of 11 minutes, although longer dives up to 45 minutes have been reported. They look very similar to dwarf sperm whales, making it very difficult to distinguish between the two species in the field. Each individual whale’s dorsal fin is a slightly different shape. For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. This species was impacted by whaling in the 18th and 19th centuries, as sperm whales were especially sought after by whalers for their sperm oil, produced by the spermaceti organ. Pygmy sperm whales can dive at least 1,000 feet in search of food. Scientists observe pygmy sperm whales to record their numbers and distribution.  The inner core of the melon has a higher wax content than the outer cortex. , Pygmy sperm whales have been reported as being forced to change their diets and foraging behaviors due to anthropological factors such as deep-sea trawling and increased fishing for cephalopods off the coast of many Southeast Asian countries. However, they were easy targets, as they tended to swim slowly and lie motionless at the surface.. Ten strandings have been recorded since 1966 primarily between Mayo to Kerry but individuals have stranded in Wexford and Dublin. Adults weigh about 400 kg (880 lb). Pygmy sperm whales enjoy temperate and tropical seas across the globe and are hard to distinguish from other dwarf sperm whales. , The pygmy sperm whale is not much larger than many dolphins. Be responsible when viewing marine life in the wild. Like its giant relative, the sperm whale, the pygmy sperm whale has a spermaceti organ in its forehead (see sperm whale for a discussion of its purpose). Usually a darker patch encircles the eye. You may also contact your closest NOAA Office of Law Enforcement field office during regular business hours. Their head is sometime described as shark-like because of their pointed snout and narrow lower jaw. Pygmy sperm whales are protected under the Marine Mammal Protection Act. Although firm details concerning pygmy sperm whale reproduction are limited, they are believed to mate from April to September in the Southern Hemisphere and March to August in the Northern Hemisphere. These groups can vary based on age and sex, but little else is known about their social organization. Our Passive Acoustics Research Group frequently makes the news. Its dive is equally lacking in grand flourish - it simply drops out of view. The pygmy blue whale may face occasional threats from whalers or poachers looking to sell their meat, however these attacks are extremely rare and their have been no major cases of these whales being attacked in recent years. They do so by producing sounds from their melons (or foreheads) that reflect off the objects around them. When i… The only pygmy sperm whale in Blue World is located in Deep Hole in Gatama Atoll. , The rostroventral dura of the brain contains a significant concentration of magnetite crystals, which suggests that K. breviceps can navigate by magnetoreception.  The positioning of this cushion structure in close proximity to the largest cavities closest to the museau de singe may suggest that it is a sound absorber used for echoreception.  Its small size also allows for it to become a byproduct of commercial fishing, caught in seine nets. Calves are weaned after 1 year. Pygmy sperm whales and their close relatives the dwarf sperm whales have similarities to the great sperm whale after which they are named. The upper jaw is destitute of teeth. Both Pygmy Sperm Whales and Dwarf Sperm Whales are widely distributed and inhabit deep tropical, subtropical and temperate waters throughout all oceans (McAlpine 2002). It was not until 2005 that genetic testing demonstrated that pygmy and dwarf sperm whales were two, not one species as previously thought and that they belonged in a separate family from the “giant” sperm whale, the family Kogiidae. Accidental vessel strikes can occasionally injure or kill pygmy sperm whales. Historically, pygmy sperm whales were hunted during the 19th century. In the upper part of the head, above the skull, there is a large cavity, or case,… Ambergris, a waste product produced by the whales, was also valuable to whalers as it was used by humans in cosmetics and perfume. Different levels of sound can disturb important activities, such as feeding, migrating, and socializing. CS1 maint: multiple names: authors list (, "Zoology of the Voyage of H. M. S.
