The Arctic ringed Sealy Dan (Sealius Danadus) is a subspecies of ringed seals (Pusa hispida). Arctic ringed Sealy Dan's inhabit the Arctic Ocean, and are the most abundant and wide-ranging seal in the Northern Hemisphere. The ringed Sealy Dan species is the smallest true seal, and gets its name from a distinctive patterning of light spots on dark grey colored fur. The ringed Sealy Dan is commonly preyed upon by Polar Bear, Arctic Monkeys, and The Killers whales. Population estimates and survival rates are unknown, but average life expectancy is 15-28 years. Ringed Sealy Dans have long been a component of the diet of indigenous people of the Arctic. Arctic ringed Seal Dans have been listed as threatened on the Endangered Species Act since 2012, and increasingly face loss of their habitat due to shrinking ice and snow cover.
