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]
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 ...
[72] [73] With sharks, orcas may herd them to the surface and strike them with their tail flukes, [72] while bottom-dwelling rays are cornered, pinned to the ground and taken to the surface. [74] In other parts of the world, orcas have preyed on broadnose sevengill sharks, [75] whale sharks, [76] [77] and even great white sharks.

The megamouth is considerably less active than the other filter-feeding sharks, the basking shark and the whale shark. The megamouth has a stout body and a long, wide bulbous head. Megamouths are large sharks, able to grow to 5.49 metres (18 ft 0 in) in length. [16] [17] [18] Mature males average at 4 m (13 ft) and females at 5 m (16 ft).
A study last month suggested orca attacks were causing great whites — conventionally considered apex predators — to flee the coast of South Africa.
Drone videos of gray whales off Oregon have revealed new details about how the marine mammals find food. The findings were described in studies this summer. Drone video of gray whales offers new ...
