At the heart of the Coral Triangle, Indonesia's Lembeh Strait is renowned for it's huge diversity and concentration of marine life. This special stretch of water is home to an astonishing array of weird and wonderful aquatic creatures. In a practice known as "muck diving", explorers seek out exotic marine animals amongst the fine sediment and discarded trash on the seabed. In the full 92-minute documentary, after the prologue, I reveal the secrets behind the Lembeh Strait's critters, exploring the marine biology of dozens of species. We encounter corals, stingrays, unusual sharks, eels, shrimps, crabs, octopus, cuttlefish, sea snails, sea slugs and of course a huge variety of tropical fish. Learn about the clever strategies such as camouflage, mimicry and symbiosis that these animals depend on in their ongoing struggle for survival on the seabed. Mucky Secrets is a fine resource for scuba divers, aquarists, students of marine biology, or anyone who is fascinated by the mysterious life that inhabits the underwater world.
