Most sharks are negatively buoyant, meaning they naturally sink in water. However, in 2015, two deep sea sharks - the bluntnose sixgill shark (top) and the prickly shark (bottom) - were discovered to be positively buoyant, meaning they naturally float in water.
This could have one of two purposes: aiding stealth hunting by enabling them to ambush prey from below by motionlessly rising towards them; or for migrating to warmer waters closer to the surface at night to warm up the muscles (to then actively swim back down to colder waters during the day).
Did you know, that like snakes and lizards, most sharks are ectothermic? This means that, normally, they’re not capable of regulating their own body temperature. However, sharks that live in frigid Arctic waters have adapted an ability called counter-current heat exchange. This method of keeping warm, allows these sharks to survive in even the coldest of the world’s oceans.
bluntnose sixgill shark has not been reported to attack people without being provoked. according to the International Shark Attack File, there has been only one documented provoked attack on a human since the 1500s. the bluntnose sixgill shark appears to be at ease in the presence of divers.

Bluntnose Sixgill Sharks are strong predators. Adults are very sensitive to and become distressed by light exposure — thus, they spend the day in the dark depths, and forage closer to the surface mainly at night. They are generalists, feeding on a great variety of prey items that are likely ambushed at close range.
