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.

large flying fox

The world's largest bat species, large flying foxes have wingspans reaching 1.5 meters and inhabit tropical forests from Southeast Asia to the Philippines and Indonesia. Despite the alarming name, they feed exclusively on fruit and nectar, making them vital pollinators and seed dispersers for tropical forest trees. Roost in massive colonies of thousands. Listed as Vulnerable due to hunting for bushmeat and habitat destruction.
