Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

An incident was filmed from a long-line trawler: a killer whale pod was systematically taking fish caught on the trawler's long lines (as the lines were being pulled into the ship) when a male sperm whale appeared to repeatedly charge the killer whale pod in an attempt to drive them away; it was speculated by the film crew that the sperm whale ...
The dwarf sperm whale is a suction feeder that mainly eats squid, and does this in small pods of typically one to four members. It is preyed upon by the killer whale (Orcinus orca) and large sharks such as the great white shark (Carcharodon carcharius). When startled, the whale can eject a cloud of red-brown fluid.
Tourists on a boat in Australia were left stunned as they watched a pod of orcas chase and attack a group of sperm whales. A rare video shows the “titans of the ocean” battling.
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 ).
An orca pod in the Pacific Ocean off the coast of Mexico has devised a cunning strategy to hunt and kill whale sharks — the world’s largest fish that can grow up to 18 meters (60 feet) in ...
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. [ 89 ]
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races , [ 1 ] subspecies , or possibly even species [ 2 ] (see species problem ).
