The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
Since 1990, over 100 countries have allowed people to eat up to 87 marine mammal species, including Indo-Pacific humpback dolphins [1] Marine mammals are a food source in many countries around the world. Historically, they were hunted by coastal people, and in the case of aboriginal whaling, still are.
Whales feed at deeper levels in the ocean where krill is found, but return regularly to the surface to breathe. There whales defecate a liquid rich in nitrogen and iron. Instead of sinking, the liquid stays at the surface where phytoplankton consume it. In the Gulf of Maine, the whale pump provides more nitrogen than the rivers. [30]
[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 Megalodon was a prehistoric shark, much like a great white ... but 60-feet long. Researchers don't actually believe it was a Megalodon, but they do think it was a giant shark: a great white ...
In fishermen's sea language, whales, dolphins, and sharks are referred to as "Ebisu" (Naumann, 1974, p. 8). If treated with respect, whales and sharks are said to chase shoals of small fish toward the shore. However, if they are enraged by loud yelling or inappropriate conduct, they can scare away the fish or do significant harm.
Orcas target the liver because it is the best way to get the most nutrients for the least effort, said the scientist. Scientist explains viral video where orcas hunt and kill a great white shark ...
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
