Tiger shark

Tiger sharks hunt like yo-yos

A joint research effort between the University of Hawaii at Mānoa's Hawai'i Institute of Marine Biology(HIMB), University of Tokyo, the Japanese National Institute of Polar Research and the University of Florida has shed new light on the hunting behaviour of tiger sharks.

Cosmopolitan predators with large home ranges, tiger sharks consume a wide variety of prey, often moving hundreds of kilometres between oceanic islands and far out into the open ocean to fill their resource needs.

Space Diving: European Astronaut Centre in Cologne

To simulate work in space, astronauts practice maneuvering equipment and gear underwater

At the European Astronaut Centre (EAC) where astronauts train for ESA’s manned space missions, trainee astronauts undergo a 16-month basic training program, and an integral part of this is to dive. Astronauts need to be underwater to practice spacewalks, also known as Extra-Vehicular Activities (EVA). Diver and underwater photographer, Christian Skauge, paid ESA’s Neutral Buoyancy Facility a visit.
