Seehund

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.

Kopfzystiden-Stachelhaut

Hyphoderma orphanellum is a corticioid fungus in the family Polyporaceae, assessed as Near Threatened (NT). It forms thin, resupinate fruiting bodies on dead wood of broadleaf trees in mature or old-growth forest environments. Its near-threatened status reflects its sensitivity to the removal of deadwood and disturbance of old-growth forests.
