Common Seal

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.

Pedobacter ruber is a Gram-negative bacterium in the family Sphingobacteriaceae, named for its distinctive red-pigmented colonies. It was isolated from soil environments and is aerobic, non-motile, and rod-shaped. Members of the genus Pedobacter are widely distributed in soil and freshwater habitats where they participate in organic matter decomposition.
