The deep sea is far below the ocean’s surface and is defined by extremes. Intense darkness, high pressure and low temperatures. These conditions aren’t suitable for all sea creatures, it takes special adaptations for animals to thrive in the deep. That’s why it’s one of the places in the ocean where some of the most otherworldly species can be found. Take a dive with us deep into the Atlantic, Arctic and Pacific Oceans off the coast of Canada to meet a few weird and wonderful animals that can be found in the ocean’s depths.
