Orca attacking a strap-toothed beaked whale. Orcas also prey on larger species such as sperm whales, grey whales, humpback whales and minke whales. [83] [39] On three separate occasions in 2019 orcas were recorded to have killed blue whales off the south coast of Western Australia, including an estimated 18–22-meter (59–72 ft) individual. [88]
An attack on a strap-toothed whale. 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.

The most common species to strand in the United Kingdom is the harbour porpoise ; the common dolphin ( Delphinus delphis ) is second-most common, and after that long-finned pilot whales ( Globicephala melas ).
Scientists say there is no credible evidence linking offshore wind farms to whale deaths. Contrary to politicians' claims, offshore wind farms don't kill whales. Here's what to know.

Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
