Water Life

Salt mines, salt flats and salt marshes seem inhospitable, but these strange and solitary places that look like otherworldly landscapes home many genuinely tough creatures who thrive while living in water with high levels of salinity.

For many creatures, the beach forms an often-hostile frontier between land and sea, yet remains an essential stopping place for penguins, land crabs, elephant seals, hermit crabs, sandpipers and other creatures as they feed, rest, mate and breed.

Stunning cinematography captures the extraordinary beauty of coral reefs. Millions of polyps construct these vast submerged cities of coral, where resourceful animals have developed ingenious survival strategies to avoid prowling predators.

Whales, sharks, jellyfish and migrating sea turtles are just some of the creatures featured in this program.
