Blastoid. 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 ... Apr 26, 2010 ...

Many of the problems associated with distinguishing crinoid species and genera exist, because it has turned out that many traditionally applied features vary with growth, habitat, depth and/or location, and because many species were originally described from one or a few specimens with little if any understanding of growth or variability among ...Habitat. Crinoids frequently live on hard substratum. Some live in areas of high current flow, usually use the vertical filtration fan posture (described in the next section). Others avoid high streams and use the radial feeding posture. Nevertheless, crinoid community is probably determined by substratum complexity, independent of water flow.Laomenes amboinensis (De Man, 1888). Ambon crinoid shrimp.

The Lagerstätte is oriented parallel to paleowave crests, and exhumed concretions indicate sediment reworking.

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.Blastoids (Phylum Echinodermata, Class Blastoidea) Blastoids are an extinct class of suspension feeding echinoderms that, like many crinoids (see above), had a body (theca) attached to a stem-like stalk that raised the body off of the bottom. The theca is marked by five major food grooves from which many thin, delicate arm-like structures known ... That’s a trend not expected to reverse.
