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.

red kangaroo

The largest kangaroo and largest marsupial on Earth, red kangaroos can stand 2 meters tall and weigh 90 kg, inhabiting the arid and semi-arid regions of inland Australia. Highly adapted to harsh desert conditions, they can survive without drinking water for long periods by extracting moisture from vegetation. Powerful hind legs enable 9-meter leaps and speeds up to 70 km/h. Males engage in ritualistic boxing contests to compete for females.
