There is no information about fin whales in areas outside of the Northern Atlantic, where they still hold the status of being endangered. A complete list of whale conservation statuses as listed by the IUCN is given below. Note that, in the case of the blue and gray whales, the IUCN distinguishes the statuses of various populations.
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]
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.
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 ...
Toothed whales can also be threatened by humans more indirectly. They are unintentionally caught in fishing nets by commercial fisheries as bycatch and accidentally swallow fishhooks. Gillnetting and Seine netting are significant causes of mortality in cetaceans and other marine mammals. [99] Porpoises are commonly entangled in fishing nets.
The explosion of animals is an uncommon event arising from natural causes or human activity. Among the best known examples are the post-mortem explosion of whales, either as a result of natural decomposition or deliberate attempts at carcass disposal. [1] Other instances of exploding animals are defensive in nature or the result of human ...
Killer whales have reportedly attacked more than 500 boats in European waters recently. Are they exacting revenge for humanity's treatment of orcas? Why are killer whales going 'Moby-Dick' on ...
The whales make groans, pops and belches typically at frequencies around 500 Hz. The purpose of the sounds is not known but may be a form of communication between whales within the same group. Northern right whales responded to sounds similar to police sirens—sounds of much higher frequency than their own. On hearing the sounds, they moved ...
