A 1.5 metres (5ft) in length male shark from the age of dinosaurs – a rare frilled shark – has been caught by researchers off Algarve coast, while working for a project to minimise unwanted catches in commercial fishing. Remains of this living fossil have been dated back 80 million years.
The fish has a long, slim, snake-like body. Its biology is little known ibecause it lives at great depths in the Atlantic and off the coasts of Australia, New Zealand and Japan. The frilled shark was caught at a depth of 700 metres (2,300 ft).
The shark gets its name from the frilled arrangement of its 300 teeth, which allows it to trap squid, fish and other sharks in sudden lunges.
The snake-like movements of this monster of the deep may have inspired sailors’ stories of sea serpents… Who knows…
