Echinoderm Printouts. Echinoderms are spiny-skinned invertebrates that live on the ocean floor. The word echinoderm means "spiny skin." No echinoderms are found in fresh water. Modern-day echinoderms have five-fold symmetry (they are pentameral), having arms or rays in multiples of five. Some fossil echinoderms did not have five-fold symmetry.Crinoids were major carbonate producing organisms during the Paleozoic and Mesozoic. In fact, in many Paleozoic and Mesozoic settings entire carbonate shelves were composed predominantly of crinoidal remains. In such examples, the enormous volume of skeletal material controlled the sedimentary environment. 26 jul 2022 ... #Crinoids are marine animals that make up the class.
