Share Tech & Science Evolutionary Biology The rare frilled shark is considered a “living fossil,” as its makeup has remained unchanged for 80 million years. This summer, researchers found one alive and thriving off the coast of Portugal, adding evidence regarding the resilience of this ancient sea creature. The shark was discovered off the Algarve coast by researchers who were working on a European Union project in the area, the BBC reported. The aim of the project was to "minimize unwanted catches in commercial fishing," but the team unknowingly unearthed one of the rarest and most ancient animals on the planet. The frilled shark has remained the same, both inside and out, since the time of the dinosaurs, with scientists dating it back to the Cretaceous Period, a time when the Tyrannosaurus Rex and Triceratops still roamed the planet. The creature is incredibly simply and unevolved, most likely due to the lack of nutrients found in its deep-sea dwellings, a previous Japanese study on the shark suggested. The examination revealed that its diet is 61 percent cephalopods—the same class that squids and octopus belong to.
