Orcas (or killer whales) are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. [2]
Fin whales, humpback whales and sperm whales have been found to have spindle neurons, whose function is not well understood, which is a type of brain cell known to exist only in certain other species of high intelligence: humans, other great apes, bottlenose dolphins and elephants.
Whales have beached throughout human history, with evidence of humans salvaging from stranded sperm whales in southern Spain during the Upper Magdalenian era some 14,000 years before the present. [2] Some strandings can be attributed to natural and environmental factors, such as rough weather, weakness due to old age or infection, difficulty ...
Pilot whales can be found in oceans nearly worldwide, but data about current population sizes is deficient. The long-finned pilot whale prefers slightly cooler waters than the short-finned and is divided into two populations. The smaller group is found in a circumpolar band in the Southern Ocean from about 20 to 65°S.
Researchers have warned that human impact on the ocean is putting increasing pressure on dolphins and whales, and their ecosystems. The UK whale and dolphin conservation charity Orca recorded ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
[17] [18] He noted that the whales were spread along 38.2 kilometres of coast and were separated by a mean distance of 3.5 km (sd=2.8, n=11). This spread in time and location was atypical, as usually whales mass strand at the same place and at the same time. At the time that Dr. Frantzis wrote the article he was unaware of several important ...
