Whale sharks possess a broad, flattened head with a large mouth and two small eyes located at the front corners. [14] [15] Unlike many other sharks, whale shark mouths are located at the front of the head rather than on the underside of the head. [16] A 12.1 m (39.7 ft) whale shark was reported to have a mouth 1.55 m (5.1 ft) across. [17]
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 ...
In other parts of the world, orcas have preyed on broadnose sevengill sharks, [76] whale sharks, [77] [78] and even great white sharks. [76] [79] Competition between orcas and white sharks is probable in regions where their diets overlap. [80] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere.
The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at high speed.
The study found that whale sharks are skilled divers, so orcas attack from below and keep the whale shark at the water's surface. Then, the orcas find a way to flip the whale shark so it's belly up.
Unprovoked attacks are initiated by the shark—they occur in a shark's natural habitat on a live human and without human provocation. [48] [49] There are three subcategories of unprovoked attack: Hit-and-run attack – usually non-fatal, the shark bites and then leaves; most victims do not see the shark.
The whale sharks were temporarily stunned and flipped over, enabling the orcas access to the lipid-rich liver of the fish. The orcas targeted the belly side likely because it is the least ...
Since its discovery in 1976, only a few megamouth sharks have been seen, with 55 specimens known to have been caught or sighted as of 2012, including three recordings on film. Like the basking shark and whale shark, it is a filter feeder, and swims with its enormous mouth wide open, filtering water for plankton and jellyfish. It is distinctive ...
