This is a prologue to my documentary “Mucky Secrets”, about the weird and wonderful marine life of the Lembeh Strait between North Sulawesi and Lembeh Island in Indonesia, one of my favorite scuba diving destinations.

At the heart of the Coral Triangle, the Lembeh Strait is known for it’s fascinating muck diving and the huge diversity of marine life. An astonishing array of weird and wonderful creatures can be encountered on every dive. Many of the animals have strong personalities, which I have tried to convey in this video. Mating mandarinfish take a starring role, as do mantis shrimps, sea slugs, snake eels, boxfish, scorpionfish, frogfish and other tropical fish and invertebrates.

In the full 90-minute documentary I reveal the secrets behind the Lembeh Strait’s critters, exploring the marine biology of dozens of species.

Thanks to Two Fish Divers ( who I stayed and dived with on Lembeh Island.
