A group of scientists on a year-long research trip have discovered a rare deep sea fish that can use its fins as if they were feet.Called Schaefer’s anglerfish (Sladenia shaefersi), the long flat creature can grow to almost five feet and weigh as much as 50 kg. It has thick and gummy skin with a distinctively mottled pattern that allows it to blend into its murky deep sea surroundings, where it subsists on a diet of other fish and can consume animals almost twice its own size.The fish was discovered around 3,000 feet below the ocean surface near Dry Tortugas, a small island in the Gulf of Mexico.
