Common Raven

One of the most intelligent birds known, common ravens demonstrate problem-solving abilities rivaling great apes, including tool use, planning, and deceptive behavior. Found across the Northern Hemisphere from Arctic tundra to deserts, ravens are highly adaptable omnivores. They form complex social hierarchies, engage in cooperative foraging, and have been observed engaging in play. Their intelligence and black plumage have made them figures of mythology across many cultures.

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.
