Mitochondrial rDNA phylogeny of the asteroidea suggests the primitiveness of the paxillosida.
Asteroids display four distinct modes of developmental patterns: the indirect mode, the nonbrachiolarian mode, the direct mode, and the mode with a barrel-shaped larva. Among them the former two areExpand

The phylogenetic status of Paxillosida (Asteroidea) based on complete mitochondrial DNA sequences.
One of the most important issues in asteroid phylogeny is the phylogenetic status of Paxillosida. This group lacks an anus and suckers on the tube feet in adults and does not develop the brachiolariaExpand

Development of a True Ovoviviparous Sea Star, Asterina pseudoexigua pacifica Hayashi.
Asterina pseudoexigua pacifica is a true ovoviviparous asteroid in that its development and metamorphosis occur within the spatial hermaphroditic gonad. From the middle of June to the middle of July,Expand

Close Relationship between Asterina and Solasteridae (Asteroidea) Supported by Both Nuclear and Mitochondrial Gene Molecular Phylogenies
Abstract Phylogenetic relationships among asteroids remain to be extremely controversial in spite of many morphological and molecular studies have been applied to this issue. In the present study,Expand

Reproduction and Development of the Conspicuously Dimorphic Brittle Star Ophiodaphne formata (Ophiuroidea)
Ophiodaphne formata is a conspicuously dimorphic ophiuroid; the disk diameters are approximately 1 mm for males and 5 mm for females. The dwarf male clings to the larger female, with the oralExpand

Neural architecture of the brachiolaria larva of the starfish, Asterina pectinifera
The nervous system of the brachiolaria larva of the starfish, Asterina pectinifera, was characterized using immunohistochemistry with the neuron‐specific monoclonal antibodies 1E11 and 1F9 and anExpand

Adhesive papillae on the brachiolar arms of brachiolaria larvae in two starfishes, Asterina pectinifera and Asterias amurensis, are sensors for metamorphic inducing factor(s)
It has been hypothesized by Barker that starfish brachiolaria larvae initiate metamorphosis by sensing of metamorphic inducing factor(s) with neural cells within the adhesive papillae on theirExpand

Functional evolution of Ets in echinoderms with focus on the evolution of echinoderm larval skeletons
Convergent evolution of echinoderm pluteus larva was examined from the standpoint of functional evolution of a transcription factor Ets1/2. In sea urchins, Ets1/2 plays a central role in theExpand

Development of the nervous system in the brittle star Amphipholis kochii
There are several studies of neural development in various echinoderms, but few on ophiuroids, which develop indirectly via the production of pluteus larvae, as do echinoids. To determine the extentExpand
