Great white shark attacks are rare, and when they do occur, they are sometimes fatal. But attacks against the human species are often a result of mistaken identity, new research published on Tuesday shows.
The study, published in the Journal of the Royal Society Interface, was conducted by looking at humans and animals from a great white shark's eye view below the ocean surface. It's often been assumed that it's hard for sharks to differentiate between them, but there is little research taking into account how sharks see, rather than just from their perspective from underwater.
Sharks, according to the research, have limited color perception if they are not completely color blind, and have spatial resolving power that is "considerably worse than humans." So when they are looking for prey, researchers found, they more heavily rely on motion and brightness contrast.

Unprecedented footage of an elusive deep-sea creature came to light this week. On an expedition through the Southern Ocean last Christmas Day, researchers discovered the Gonatus antarcticus, a mysterious species of squid known to roam the freezing waters around Antarctica but never seen alive before in its natural habitat.

London — President Trump declared on Wednesday morning that a U.S. trade "deal with China is done."

Jerusalem — Israel deported activist Greta Thunberg on Tuesday, the country's Foreign Ministry said, a day after the Gaza-bound ship she was on with 11 other people was seized by the Israeli military. Thunberg left on a flight to France and was then headed to her home country of Sweden, the Foreign Ministry said in a post on X. It posted a photo of Thunberg, a climate activist who shuns air travel, seated on a plane.
