Marine biologists have spotted an intriguing behavior of fish chafing themselves against a shark's skin in over a dozen locations worldwide. What could be the possible ecological function of this serving both species?
A fishing expedition 15 years ago off the west coast of Greenland led scientists to discover the world's oldest vertebrate, Greenland sharks. This species can live at least 250 years up to 500 years old.
An analysis of Discovery Channel's Shark Week documentary programming showed that it actually harms sharks, shark science, and shark scientists instead of helping the conservation efforts of the species.
As scientists at various institutions are directly focusing on shark conservation, the Earth-observing satellites of NASA collect important information about the habitat of sharks, the ocean, in particular.
Hollywood movies about sharks overwhelmingly portray the apex predators in a negative light, which makes it harder for shark conservation efforts. Much of this impact stems from the 1975 blockbuster movie "Jaws."
