How does the position of the mouth and anus of a crinoid relate to a primitive sessile existence?

The mouth of the crinoid is located right next to the mouth and their digestive system is u-shaped. This is perfect in a sessile existence because, if they attach themselves to a surface, both the mouth and anus will be able to function.
