It looks like a molar tooth drenched in gold, or maybe a metallic mylar birthday balloon. But this is a bathypelagic ctenophore, photographed near the Mid-Atlantic Ridge of the Atlantic Ocean. The ‘bathypelagic zone’ is the layer of the ocean about 3,000 – 13,000 feet deep, sometimes called “The Midnight Zone”, because there is no light at these depths.
Ctenophores are known to many as comb jellyfish – they have eight rows of cilia that look like combs, which they use to move through the sea. Researchers say this one anchors to the seafloor with its tentacles.
Researchers collaborating on the Census of Marine Life returned from an expedition to the Mid-Atlantic Ridge, brimming with findings of new creatures, reporting on unexpected abundance of some already-known creatures, and sharing stunning photos (like this one) with the world.
“This expedition has revolutionised our thinking about deep-sea life in the Atlantic Ocean. It shows that we cannot just study what lives around the edges of the ocean and ignore the vast array of animals living on the slopes and valleys in the middle of the Ocean,” said Professor Monty Priede, Director of the University of Aberdeen’s Oceanlab.
