Last week, a new study revealed Chilean devil rays to be some of the oceans' deepest-divers, often taking dives deeper than a mile under the water's surface.

Following the study's findings, Oceana in Europe's Angela Pauly took a close look at the Chilean devil ray. This blog first appeared on Oceana in Europe's blog.
