Part 2 of my documentary, “Mucky Secrets”, about the marine life of the Lembeh Strait in Indonesia. Anemonefish, shrimps and mantis shrimps.

In this video we take a look at the mutually symbiotic relationship between saddleback clownfish, a type of anemonefish, and the sea anemones found in the Lembeh Strait. The anemone’s stinging tentacles provide protection for the clownfish, which are immune to the sting. The clownfish chase sway polyp-eating predators, and their feces provide food for the anemone.

We then see how partner shrimps (commensal shrimps) also benefit from a commensal relationship with sea anemones. The shrimps use the anemone’s tentacles for protection, but the anemone doesn’t appear to benefit in any way.

We then take a look at emperor shrimps and sexy shrimps (squat shrimps), then finally at mantis shrimps. A number of different species of spearing mantis shrimps and smashing mantis shrimps live in the Lembeh Strait. They all have extremely advanced eyes and a very fast attack with their claws.

Thanks to generalfuzz and Kevin MacLeod for the music.

I have finally completed my documentary, “Mucky Secrets”, about the fascinating marine life of the Lembeh Strait, and here is the first part. I intended to serialise the whole documentary on YouTube over the next few weeks, so please subscribe to my channel to follow along.

In this video I introduce the Lembeh Strait’s location off North Sulawesi, in Indonesia, at the heart of the Coral Triangle. The Coral Triangle has been designated on account of its extraordinary marine biodiversity, and the Lembeh Strait hosts a huge variety of marine critters on its seabed of dark, volcanic sand and silt. The type of exploration it offers has become known as “muck diving”. The conditions and cryptic critters of the Lembeh Strait contrast with the clear blue water and coral reefs of dive locations such as the nearby Bunaken National Park.

I introduce some of the sessile animals that live in the Lembeh Strait, including corals and sea squirts, otherwise known as tunicates or ascidians, enjoying the currents at dive sites such as Critter Hunt.

Thanks to Two Fish Divers, especially to their keen-eyed critter-spotting dive guides, and to Klangachse and Purple Planet for the music.

I’ve been working on a 90-minute documentary called “Mucky Secrets”, about the weird and wonderful marine life of Indonesia’s Lembeh Strait, one of my favorite muck diving destinations.

Here’s a prologue I made in advance of the full release. I really tried to show the personalities of all these quirky little creatures.

Thanks to Doxent Zsigmond for the beautiful music track “Journey”, and to Two Fish Divers, who I stayed and dived with.

Please subscribe to the Bubble Vision YouTube channel for notification of the release of the full documentary.

(A new, re-titled version of my DVD, “Reef Life of the Andaman” for Italy, with a fine commentary in Italian)

Marine Life Video for Schools & Universities

I’m delighted that “Reef Life of the Andaman” is now being distributed to the educational market by, the leading source in this field.


Both DVD and streaming versions are available with appropriate rights for schools, universities etc.. The 116-minute documentary is a great resource for marine biology students and anyone interested in life under the sea.

(As always the home version is available at

My DVDs are now manufactured and shipped by CreateSpace, a subsidiary of Amazon, and I designed a new sleeve for my “Diving in Bali” DVD. You can still find them at

How many fish do you see in this video? Answers in the comments please. If you think you know the species (common name or scientific name), please add that too.

Mist rolls across the reservoir on a fresh morning at Pang Ung (ปางอุ๋ง) near Mae Hong Son: Thailand’s own little Switzerland. This is another video shot with my little Sony RX100 compact camera. Watch in HD and feel the chill! Thanks to Klangachse for the beautiful piano music.

In January I travelled around Mae Hong Son in north Thailand. We visited the village of Kayan Tayar, and I took some shots with my little Sony RX100. One of the Kayan Lahwi long-neck women sang and played us a tune.

This is the first video on my new YouTube channel for non-diving videos. Please subscribe (below the video on YouTube) if you’re interested in more.
