Venture Arctic they survive based upon their large numbers. Arctic fox - The Arctic fox hunts for small rodents and birds in the summer. In the winter months when food is scarce the Arctic fox becomes a scavenger, often following polar bears or wolves to feast on the remains of their prey. Arctic hare - The Arctic hare is particularly suited to escaping predation on the icy tundra. They are very fast, traveling at speeds up to forty miles per hour. Their blue-grey pelt turns pure white in the winter to help camouflage them from predators. Arctic wolf - Arctic wolves reside
Ocean acidification in the Arctic Ocean simulation predicts that Arctic surface waters will become undersaturated with aragonite within a decade. The undersaturation of aragonite will cause the shells of organisms which are constructed from aragonite to dissolve. This would have a profound effect on a large variety of marine organisms and has the potential to do devastating damage to keystone species and to the marine food web in the arctic ocean. Laboratory experiments on various marine biota in an elevated CO₂ environment show that changes in aragonite saturation cause substantial changes in overall calcification rates for many species of marine organisms, including coccolithophore, foraminifera, pteropods, mussels,
