Researchers from Portugal’s Institute for the Sea and Atmosphere found a rare frilled shark off the coast of the Algarve.
The prehistoric beast has been swimming the seas for up to 80 million years judging by remains which have previously been found.
This means the species has lived during the cretaceous period. Experts have dubbed it a “living fossil”.
Other beasts that lived during the cretaceous period include the Tyrannosaurus Rex, velociraptors, and the baryonyx – a relative of the T-Rex.
