Race to Survive – Pacific walrus travel according to the movement of the ice. As the ice expands in the winter, they move south. As it breaks up and retreats in the spring and summer, they move north again. (Photo Credit: © NGT)
Feast or Famine – Jellyfish Lake, Palau: Five million jellyfish glide across the lake’s surface each day to follow the sun – streaming eastward in the morning and westward in the afternoon – in a stunning daily migration. At night, the jellyfish sink down 45 feet to absorb nutrient-rich bacteria, which the algae in their bodies require to survive. (Photo Credit © NGT)
