Off the coast of Portugal near the Algarve region, a group of researchers accidentally caught a frilled shark.

The frilled shark is a member of the Chlamydoselachidae family, a species rarely seen by humans as it spends most of its life in abyssal depths, the frilled shark has been caught incidentally by commercial fishermen before in areas like Suruga Bay in Japan.

Dr. Margarida Castro, a professor and researcher at the Centre for Marine Sciences at Portugal's University of Algarve told BBC Brazil "From this depth, most fish come up dead." "The net goes up very fast, and they do not survive the sudden change of pressure."

Frilled sharks are given it's name because due to their gills and it is believed that they primarily feed on cephalopods.
