This video is called Diving Indonesia – Grey Reef Sharks.
Translated from Dutch NOS TV:
At Indonesian fish markets, at least twenty new species of rays and sharks have been discovered.
Australian researchers went to these markets in the five past years in order to photograph and describe fishes.
According to the Australians, before their research started, still much was unknown about sharks and rays in Indonesia.
There are more sharks and rays there than anywhere else in the world.
Each year, over 100,000 tons are caught.
Ever since Dutch researcher Pieter Bleeker between 1842 and 1860 described over 1100 fish species in Indonesia, there has not been such intensive research into new fish species there.
