Scientists made a horrifying but interesting discovery off the Portuguese coast after a trawler found what appeared to be a dinosaur-era shark with a snake's head and 300 teeth. The species dates back to 80 million years ago. University of the Algarve professor Margarida Castro explained to Sic Noticias the purpose behind the shark's numerous teeth, claiming the creature's unorthodox jaw allows it to "trap squid, fish and other sharks in sudden lunges." It is believed the shark lives in the Atlantic, and more importantly, it roams in waters near Australia, New Zealand and Japan. 

Given this scary discovery, people are understandably hesitant to go anywhere near those waters now. 

Same.
