Palau is a tiny country with a big story. In 2009, this island nation in the middle of the western Pacific Ocean created the world's first shark sanctuary to protect more than 100 shark species from reckless overfishing and the brutal practice of commercial shark finning. Then, in 2014, Palau once again led the way. It established the world's largest marine sanctuary - a no-go zone for foreign commercial fisheries nearly the size of California.

Every year in the dry season, as the floodwaters disappear, the grasslands of the Pantanal are home to many species: giant anteaters, maned wolves and the greater rheas- the largest bird in South America.

New Zealand's West Coast is like nowhere else on Earth. From glacier-covered mountains to rain-drenched native forests to rough frigid seas, the landscape defies belief. Isolated from the rest of the world, this strip of almost untouched wilderness hides a host of endemic animals. Evolutionary castaways, every one of them is a rare ecological jewel. From alpine parrots and shy penguins to mammal-like kiwis and ancient eels. To survive the conditions the wildlife here has to be hardy, cunning and resourceful. A journey along the West Coast reveals the beauty of this land, and the trials and tribulations of the wildlife that live here.

Its reef, one the largest living structures on the planet, is home to more than 1,500 species of fish.

At the southern edge of the Pantanal, in one of the world's largest tropical wetlands, Biologist Carolina Ribas and her local guide, Arilei Terena search for a giant otter den. Despite their large size, noisy and gregarious nature, endangered giant otters are notoriously shy and hard to find.
