Bog Aster

The Bog Aster (Oclemena nemoralis) is a species in the genus Oclemena. It is currently classified as Least Concern on the IUCN Red List. Distributed across Canada, France, and United States.

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.
