Squat lobsters, hermit crabs, true crabs and sea urchins. Part 3 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video we first look at more marine crustaceans. First we meet squat lobsters. The elegant squat lobster, Allogalathea elegans, lives commensally on the arms of crinoid feather stars. It feeds on plankton collected by its host, and its colour often matches the crinoid for camouflage.

Next we encounter squat lobsters of the Galathea genus fighting for territory on branching sponges at TK 2.

Hermit crabs don't have a hard carapace like other crabs, so they recycle an empty gastropod shell to protect their soft abdomen. They carry their adopted home around with them, and long eye stalks ensure that the crab has a wide angle of view. We encounter whitespotted hermit crabs, Dardanus megistos, living in empty cone shells and conch shells. We also meet an anemone hermit crab, Dardanus pedunculatus, carrying sea anemones on its back in a classic example of mutual symbiosis.

We then meet a pair of box crabs, Calappa sp.. The male box crab carries the female everywhere with him until she has moulted her shell and is ready to mate.

Camouflage is important for Lembeh's true crabs. We encounter a rear-spined elbow crab, Aulacolambrus hoplonotus, and a decorator spider crab, Achaeus sp., perfectly camouflaged in their environment.

A zebra crab, Zebrida adamsii, clings to the spines on the underside of a highly venomous flower urchin, Toxopneustes pileolus, using the last segment of its legs which has evolved into a hook.

Blue-spotted urchins, Astropyga radiata, are also highly venomous and gather in groups at dive sites such as Hairball. Juvenile emperor red snappers, Lutjanus sebae, often shelter amongst these sea urchins in a commensal relationship.

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 music tracks are "Mountain Breeze (pad)" by Purple Planet (http://www.purple-planet.com) and "Arrival of the Broken Kings" by Klangachse (http://klangachse.de).

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.
