The fascinating migration of tuna | Full Documentary

Tuna are among the world’s most coveted fish. For millennia they were the Mediterranean’s “manna,” but industrial fishing has pushed many species to the brink—only about 8% of their former population remains. Marine biologist Boris Frentzel-Beyme follows the tuna migration from the Atlantic to the Mediterranean, visiting suspected spawning grounds and meeting fishermen and experts along the way. His dives reveal rare Mediterranean wildlife and never-before-filmed species. Using deep-sea technology, scientists explore wrecks, hot vents, and encounter elusive sharks such as the bluntnose sixgill and ragged-tooth. In Croatia, they film the massive basking shark and digitally reconstruct ancient giants like the megalodon and giant mako. ➡ Subscribe: https://tinyurl.com/FreeHighQualityDo... #fullepisode #animals #documentary #wildlife #tuna #ocean
