A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain...

A Hawaii University team trained six sandbar sharks and one scalloped hammerhead shark to associate food with an artificial magnetic field, they report in a publication of Britain's Royal Society. The field, derived from a copper coil surrounding the sharks'...
