In the prestigious series Treatise on Invertebrate Paleontology<\/em><\/a>, a chapter was released that synthesizes data on the functional morphology and paleoecology of crinoids<\/a> with unusual morphologies. It illustrates how, over more than 485 million years, they repeatedly deviated from their original body plan: from benthic forms to pelagic species. Some forms lost their arms, others transformed their holdfasts into bulbs, or developed extremely long stems. These examples highlight the remarkable morphological plasticity of crinoids and their ability to occupy diverse ecological niches<\/a>.<\/p>
