Mucky Secrets (full) - The Marine Creatures of the Lembeh Strait

  • "Mucky Secrets" is a documentary about the marine life of the Lembeh Strait at the heart of the Coral Triangle off north Sulawesi in Indonesia. The DVD is available at

    The Lembeh Strait is a popular scuba diving destination, famed for its excellent "muck diving". A huge diversity of exotic marine creatures can be found on the mucky seabed, including everything from tropical fish to benthic sharks to nudibranchs. Critters compete for survival with an armoury including camouflage, mimicry, toxicity, and dazzling coloration.

    "Mucky Secrets" is an excellent resource for scuba divers, aquarists, and marine biology students. The documentary features underwater macro footage from many of Lembeh's famous dive sites including Critter Hunt, Police Pier, Tanjung Kusu-Kusu, Nudi Falls, Aer Perang, Jahir, Makawide, Nudi Retreat, Retak Larry, TK (Teluk Kembahu), Hairball and Aw Shucks.

    There are subtitles/CC tracks for the narration and for the scientific and common names of the marine species, and dive site names.
