According to Sic Noticias TV, scientists caught the prehistoric shark while working on a project to “minimize unwanted catches in commercial fishing” at a depth of 2,300 feet below the surface of the water off the coast of Portugal.

The shark has been named the “frilled shark” because it has extra gills and strangely configured rows of teeth. It measured in at about five feet in length.

Unfortunately, that’s about all that’s known about the “frilled shark.” Scientists have struggled to research its biological make-up or its exact environment, but they are confident it prefers to live at deep depths.

Because of this, it makes it difficult to study the animal in its natural habitat not to mention quite costly.
