Orca attacking a strap-toothed beaked whale. Orcas also prey on larger species such as sperm whales, grey whales, humpback whales and minke whales. [84] [40] 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 ...
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. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the ...
Historically, whaling took a heavy toll on sperm whale populations. Prior to the early 18th century, sperm whales were hunted in Japan and Indonesia. Legend has it that sometime in the early 18th century, supposed to be not far from 1712, Captain Christopher Hussey, while cruising for right whales near shore, was blown offshore by a northerly wind, where he encountered a school of sperm whales ...

Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...
[1] [3] [4] [24] It is assumed that the hunting tactics of Livyatan for hunting whales were similar to that of the modern killer whale, pursuing prey to wear it out, and then drowning it. [1] [25] Modern killer whales work in groups to isolate and kill whales, but, given its size, Livyatan may have been able to hunt alone. [26]
This includes the sperm whale, oceanic dolphins, usually pilot and Orcas, and a few beaked whale species. 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 ).
The most common natural predator of sperm whales is the orca (killer whale), but pilot whales and false killer whales sometimes harass them. [ 195 ] [ 196 ] Orcas prey on target groups of females with young, usually making an effort to extract and kill a calf.
