fine structure of spermatogonia, spermatocytes, and spermatids of the sea cucumbers cucumaria lubrica and leptosynapta clarki (echinodermata: holothuroidea).		1974	4434278
molecular phylogeny of pacific archigregarines (apicomplexa), including descriptions of veloxidium leptosynaptae n. gen., n. sp., from the sea cucumber leptosynapta clarki (echinodermata), and two new species of selenidium.	although archigregarines are poorly understood intestinal parasites of marine invertebrates, they are critical for understanding the earliest stages in the evolution of the apicomplexa. previous studies suggest that archigregarines are a paraphyletic stem group from which other lineages of gregarines, and possibly all other groups of apicomplexans, evolved. however, substantiating this inference is difficult because molecular phylogenetic data from archigregarines, in particular, and other grega ...	2012	22515299
novel insights into the echinoderm nervous system from histaminergic and fmrfaminergic-like cells in the sea cucumber leptosynapta clarki.	understanding of the echinoderm nervous system is limited due to its distinct organization in comparison to other animal phyla and by the difficulty in accessing it. the transparent and accessible, apodid sea cucumber leptosynapta clarki provides novel opportunities for detailed characterization of echinoderm neural systems. the present study used immunohistochemistry against fmrfamide and histamine to describe the neural organization in juvenile and adult sea cucumbers. histaminergic- and fmrfa ...	2012	22970182
