A little-known frilled shark has been found off the Algarve coast in Portugal by scientists, who were conducting research on minimising unwanted catches in European fisheries. The shark was caught at a depth of 700 meters and its remains have been unchanged for 80 million years. The male shark measures about 1.5 meters long and has a long, slender body and a snake-like head. It has a unique teeth arrangement, but there’s little else known about the shark’s biology or ecology. The shark gets its name from the frilled appearance of its gills and its 300 teeth allow it to trap squid, fish, and other sharks in sudden lunges.
