Unlike stalked crinoids, the Saccocoma pectinata was a free-floating species that fed on plankton. It is believed that the Saccocoma pectinata could swim using its feathered arms to propel itself through the water. These crinoids have been excellently preserved in the Solnhofen Limestone with some specimens even retaining their feathery arm structures.
