In hopes of understanding the marine environments of the Earth, scientists make use of underwater drones. This same method is also being used by scientists working at NASA, but the difference is that they are developing an “intelligent” kind which would help them study Jupiter’s moon, Europa.
A drone that can fly in the air and swim underwater has been built by researchers at Rutgers University The "Naviator" drone got the attention of the US Navy, which has provided funding for its continued development.
Using a special SharkCam, researchers have filmed the underwater predatory behaviors of great white sharks for the first time. It appears they lurk in the darkness before ambushing their prey from below. While this new study offers groundbreaking insight, researchers say there is still much to learn about these mysterious fish.
