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. The rays' physiology hinted at this discovery, since they do have a retia mirabilia—an organ found in other deep-divers like great white sharks. 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.
You may not have heard of sawfish, an incredibly unique looking family of rays.

Despite their large size (up to 20 feet long!) and those intimidating teeth, sawfish are in trouble.
