The name "whale shark" refers to the animal's appearance and large size; it is a fish, not a mammal, and (like all sharks) is not closely related to whales. [13] In addition, its filter feeding habits are similar to baleen whales .
The shark recorded instigating the attack was a female nicknamed "Helen". Working alone, the shark attacked a 33 ft (10 m) emaciated and entangled humpback whale by attacking the whale's tail to cripple and bleed the whale before she managed to drown the whale by biting onto its head and pulling it underwater.

Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος () 'huge fish, sea monster') [3] is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.
Basking sharks, whale sharks, and megamouth sharks have independently evolved different strategies for filter feeding plankton: basking sharks practice ram feeding, whale sharks use suction to take in plankton and small fishes, and megamouth sharks make suction feeding more efficient by using the luminescent tissue inside of their mouths to ...
The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow rostrum, bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
In other parts of the world, orcas have preyed on broadnose sevengill sharks, [75] small whale sharks [76] and even great white sharks. [75] [77] Competition between orcas and white sharks is probable in regions where their diets overlap. [78] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere.
This position with the flukes above the water is known as "whale-tail-sailing." Not all whale-tail-sailing includes nursing of the young, as whales have also been observed tail-sailing while no calves were present. [67] Being mammals, they have mammary glands used for nursing calves; weaning occurs at about 11 months of age.
