Plated Cambrian Bilaterians Reveal the Earliest Stages of Echinoderm Evolution [PDF]

open access: yesPLoS ONE, 2012
Echinoderms are unique in being pentaradiate, having diverged from the ancestral bilaterian body plan more radically than any other animal phylum. This transformation arises during ontogeny, as echinoderm larvae are initially bilateral, then pass through

Fertilization in echinoderms

Biochemical and Biophysical Research Communications, 2012
For more than 150 years, echinoderm eggs have served as overly favored experimental model systems in which to study fertilization. Sea urchin and starfish belong to the same phylum and thus share many similarities in their fertilization patterns.

Paleogenomics of Echinoderms

Science, 2006
Paleogenomics propels the meaning of genomic studies back through hundreds of millions of years of deep time. Now that the genome of the echinoid Strongylocentrotus purpuratus is sequenced, the operation of its genes can be interpreted in light of the well-understood echinoderm fossil record.

The sterols of echinoderms

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1972
Abstract The pioneering work of Bergmann and his colleagues demonstrated that marine invertebrates in many cases contain complex sterol mixtures consisting of C27, C28 and C29 sterols of varying degrees of unsaturation (Bergmann 1949, 1962). The sterols found in the phylum Echinodermata have proved of particular interest not only from
