Blastoids (BLAS-toyds) are extinct, stalked, invertebrate animals that were related to crinoids. Like crinoids, blastoids had an upward-facing mouth near the top of the body (theca). They differed from crinoids in that, instead of true arms, blastoids had long, delicate appendages called brachioles. These caught suspended particles on ... Crinoids. Crinoids are echinoderms, related to sea urchins and sea stars. These invertebrate animals feed by using their arms to filter food out of the water. Most are attached to the sediment by a stalk that ends in a root-like structure called the holdfast—some forms, however, are free floating. Holothuroidea: Holothuroidea, commonly known as sea cucumbers, have a unique skeletal structure called "ossicles." Ossicles are small, calcareous plates embedded in the sea cucumber's body wall. These plates provide support and protection.

Chan, S.-W. Ontogenetic changes in feeding ecology and habitat of the damselfish ... Therefore, with both habitat shifts and the significance of predation-driven extinction, a more complex dynamic than simple taxonomic turnover existed. The overall structure of Mississippian crinoid faunas was a function of endemic origination, migration, and predator-prey dynamics.The diversity of species in a given crinoid habitat is driven by factors such as the amount of sediment suspended in the water, the strength of currents at various levels above sea bottom, the nature of the substrate, presence of predators, etc. ReproductionArticle citations More>>.

May 31, 2016 · For feeding, they form a characteristic parabolic filtration fan with their arms recurved backwards into the current. The fossil record, in contrast, provides a large number of stalked crinoids that lived in shallow water settings, with more rapidly changing flow velocities and directions compared to the deep sea habitat of extant crinoids.
