From the dark, chilly waters they materialized—massive beings with large eyes that I knew were watching my every move from deep below long before I ever saw them.
The fish were nearly 10 feet in length and several feet thick, weighing around 1,000 pounds, and moved unlike anything else I had seen underwater.
Spinning around in circles I would see them rocket up from the depths, turn on a dime while flashing colors, then disappear back into the gloom. At least a dozen of them swam around me, and I scanned all axes trying to follow their movements. As they passed by I rolled in the wake of their mighty bulk.
Mesmerized by this fluid scene, I forced myself out of the trance I was in and began making pictures, but just kept repeating over and over in my head, “these are perfect oceanic creatures.”
They were the creatures that had haunted my dreams and stirred my soul. Feeling at times like Ahab, I’d pursued these animals for almost two decades; a quest not to capture, but to photograph.
And finally, I was here, on assignment for National Geographic magazine, tasked with bringing back images of these elusive and enigmatic beasts. I was in the northern realm of the last of the giants.
They can be as big as great white sharks, but that’s about as far as the comparison goes.
Their maximum speed is a lethargic 1.7 miles per hour, many are almost blind, and they are happy to eat rotting carcasses.
They may be common throughout the ocean, but you’ve probably never heard of them. Meet the Greenland shark.
Looking like nothing so much as a chunk of weather-beaten rock, Greenland sharks (Somniosus microcephalus) can grow up to 7.3 metres (24 feet) long, making them one of the largest of all fish, and the biggest in the Arctic.
But they prefer to live in deep, cold water, so humans rarely see them.
Studies in the Arctic have revealed a few snippets of information about Greenland sharks, and more data is now starting to come in from elsewhere.
It turns out that Greenland sharks are bizarre, and may be crucially important for the ocean ecosystem.
Greenland sharks only come close to the surface in places where the shallow water is frigid enough for them – primarily in the Arctic.

Up to 2m long the ribbonfish is an elegant deep-sea creature.
Named for the elaborate fins that ripple delicately after them as they swim, ribbonfish from the genus Trachipterus are found all over the world.
There are six known species, and Australia’s is the southern ribbonfish, a 2m-long silvery creature with black polka dots on its sides and bright red fins.
Found off the coast of southern Queensland and South Australia, the southern ribbonfish has also set up a population off the coast of South Africa.
This fish is pretty much a taxonomic nightmare, because while it’s certainly a single species, according to the Australian Museum no one can decide whether its correct scientific name is T. jacksonensis or T. arawatae.
