For example, a sea urchin has an 'echinopluteus' larva while a brittle star has an 'ophiopluteus' larva. A starfish has a 'bipinnaria' larva, which develops into a multi-armed 'brachiolaria' larva. A sea cucumber's larva is an 'auricularia' while a crinoid's is a 'vitellaria'. All these larvae are bilaterally symmetrical and have bands of cilia with which they swim; some, usually known as 'pluteus' larvae, have arms. When fully developed they settle on the seabed to undergo metamorphosis, and the larval arms and gut degenerate. The left hand side of the larva develops into the oral surface of the juvenile, while the right side becomes the aboral surface. At this stage the bilateral symmetry is lost and radial symmetry develops. The planktotrophic larva is considered to be the ancestral larval type for echinoderms but after 500 million years of larval evolution, about 68% of species whose development is known have a lecithotrophic larval type. The provision of a yolk-sac means that smaller numbers of eggs are produced, the larvae have a shorter development period, smaller dispersal potential but a greater chance of survival. There seems to be an evolutionary trend towards a "lower-riskblower-gain" strategy of direct development. Distribution and habitat Echinoderms are globally distributed in almost all depths, latitudes and environments in the ocean. They reach highest diversity in reef environments but are also widespread on shallow shores, around the poles b refugia where crinoids are at their most abundant b and throughout the deep ocean, where bottom-dwelling and burrowing sea cucumbers are common b sometimes accounting for up to 90% of organisms. While almost all echinoderms are benthic b that is, they live on the sea floor b some sea-lilies can swim at great velocity for brief periods of time, and a few deep-sea sea cucumbers are fully floating. Some crinoids are pseudo-planktonic, attaching themselves to floating logs and debris, although this behaviour was exercised most extensively in the Paleozoic, before compet ------------------------------ End of alt.music.moxy-fruvous digest V14 #7954 **********************************************
