Study shows that devil rays dive deep
Dr Simon Thorrold, an ocean ecologist at the Woods Hole Oceanographic Institute and a team have published a paper in the journal Nature Communications showing the results from tagging 15 Chilean devil rays (Mobula tarapacana) with special satellite tags. The findings include the amazing fact that they dive to depths of up to 1,848m (6,063 ft). (Image from Shutterstock)
