Barnacles belong to the class Cirripedia, which is a subclass of the class Maxillopoda.

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. 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 ...

In life, the theca of a typical blastoid was attached to a stalk or column made up of stacked disc-shaped plates. The other end of the column was attached to the ocean floor by a holdfast, very much like stalked crinoids. The stalk was usually relatively short, and in some species, was absent, with the holdfast being attached directly to the ...Malaysia | State: Sarawak. 4,707.1 km2 (1,817.4 sq mi) 21.95 m (72.01 ft) 356, 900 (as of 2020) MST (UTC+8) +6085 (landline only) City on the move.

Today, stemless crinoids live in a wide range of ocean environments, from shallow to deep, whereas their relatives with stems normally live only at depths of 300 feet or more. These modern crinoids are an important source of information about how the many different extinct crinoids lived.

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.Stock image 4421-24185: Coral reef habitat, with crinoid and fish, Morgue dive site, Christmas Island, Australia.Jun 23, 2014 ...
