YouTube Description

as posted by the channel

Normally, scientists have to “fish” for deep sea sharks, bring them up to the surface, measure them and then tag them in order to learn vital scientific information about them. But that really stinks for a shark. On the surface, it’s way hotter, way brighter and the pressure is way different. It can really stress them out. Sometimes fatally.

That’s why, for the first time ever in 2019, a team of researchers on one of our missions in The Bahamas tried out a new method... tagging a deep sea shark from an OceanX submersible. They basically devised a way to trigger a spear gun from inside the sub, which, if done right, will implant a tag into the sharks. This had never been done before. This is the kind of impossible science we love to tackle at OceanX.
