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

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.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.

"Mucky Secrets" is being serialised weekly on YouTube. Please subscribe to my channel to receive notifications of new episodes as I release them. The series will feature a huge diversity of weird and wonderful marine animals including frogfish, nudibranchs, scorpionfish, crabs, shrimps, moray eels, seahorses, octopus, cuttlefish etc..

The video was shot by Nick Hope with a Sony HVR-Z1P HDV camera in a Light & Motion Bluefin HD housing with Light & Motion Elite lights and a flat port. A Century +3.5 diopter was used for the most of the macro footage.
