Just a while ago, a previously unexplored region of the Indian Ocean gave us more than 11 new species to look forward to reading about, including crustaceans with fascinating appearances and others. This is an amazing breakthrough for marine biology. But accomplishments in the field just seem to keep coming, as scientists from Oxford University travel Bermudian waters to discover a new area.
But that’s not yet the amazing part — the newfound ocean zone they call Rariphotic Zone (or rare light zone) seems to be home to 100 previously unknown species as well.
[M]ore than 100 new species were discovered including tanaids – minute crustaceans – dozens of new algae species and black wire coral that stand up to two metres high . . . The survey team spent hundreds of hours underwater, either scuba diving or using submersibles and remote operated vehicles which can reach depths of 6,500 feet (2,000m).
The team of marine biologists also found a huge algal forest on an underwater mountain about 15 miles from the Bermudian coast. Gardens of corals populated by urchins, eels, crabs, fish, and other creatures were also discovered to exist on this mountain’s slopes. For reference, the world has a total of around 100,000 underwater mountains, with only 50 that have been intimately explored by scientists.
Alex Rogers, Professor of Conservation Biology at Oxford University and scientific director of Nekton — the British charity which organized the ocean exploration trip — has a rightful opinion. The discovery of an entirely new ocean zone forwards the idea that there is far more diversity to look into. We may not have even laid eyes on so many ocean species.
“The average depth of the ocean is 4,200m. If life in the shallower regions of the deep sea is so poorly documented it undermines confidence in our existing understanding of how the patterns of life change with depth,” he added.
“[This is] evidence of how little we know and how important it is to document this unknown frontier to ensure that its future is protected”.
What he’s saying is very significant. Huge actions towards marine conservation are happening, such as Australia’s 500 million dollar pledge to the protection of the Great Barrier Reef. But if we really want to protect the oceans and marine life, first we need to know in detail what we are protecting. And there is so much left to know.
