In this study, shallow-water crinoid populations and their symbiotic communities from the Bangka Archipelago (North Sulawesi, Indonesia) were investigated.

Crinoid Shrimp have a maximum body length of some 25 to 30 millimeters and the colors vary greatly between the different species and even possibly within the species. The colors match the host crinoid’s colors and they are extremely well camouflaged. One has to look quite carefully to spot the specimen below in the center of the ...... crinoids, but corresponds to the assumed habitat. A few general growth gradients seem to control this and other adaptive modifications of the crinoid stems.Habitat. Crinoids frequently live on hard substratum. Some live in areas of high current flow, usually use the vertical filtration fan posture (described in the next section). Others avoid high streams and use the radial feeding posture. Nevertheless, crinoid community is probably determined by substratum complexity, independent of water flow.

Many crinoids existed during the Paleozoic fossil era. Today, they live in the western part of the Pacific Ocean and the Atlantic Ocean. Crinoids inhabit deep waters and attach themselves to the ocean floors. They can live as deep as over 9,000 meters from the surface of the water. Consequently, they are rarely seen by man.The crinoid habitat is mainly found in Grand Bahamas islands, marine regions of North America and Australia at the great barrier reef with a lot of diversity and also across Japan and West Indies.
