Scientists dropped a cow carcass over 1,600 meters deep in the South China Sea, expecting chaos—but instead, eight Pacific sleeper sharks showed up and politely took turns snacking! Not only did these deep-sea predators surprise everyone with their manners, but their appearance in this region has researchers questioning what we really know about where these sharks live. Also, people can’t get over their creepy, toothy 'smiles' caught on camera. Nature is wild! #Science #DeepSeaMystery #SharkWeek
