Scientists warn that as they learn more about the incredible evolutionary traits of the iceberg-dwelling snailfish, time is not on their side. Read more:
“We were diving both day and night under the ice, and it felt like diving in molasses,” said Gruber, a biology and environmental sciences professor at CUNY's Baruch College. “The fish were really slow and sluggish living in such a cold environment, and it was just amazing how this fish is surviving in this extreme environment and not freezing.”David Gruber and John Sparks on an iceberg in eastern Greenland.
Researchers sequenced the snailfish’s DNA in a lab to discover all the proteins the animal produces. The antifreeze protein was in the highest abundance. Swimming among the icebergs, Gruber also observed a lot less biodiversity than he expected in the Arctic waters. According to the study, only 270 or so fish species live in those chilly waters — and of those, 15 varieties live there and nowhere else in the world.David Gruber and John Sparks under the ice in the waters off eastern Greenland.
