Conservation of mitochondrial genome arrangements in brittle stars (Echinodermata, Ophiuroidea)
Molecular Phylogenetics and Evolution, 2019Brittle stars are conspicuous members of benthic ecosystems, fill many ecological niches and are the most speciose of all classes of echinoderms. With high levels of biodiversity, elucidating the evolutionary history of this group is important. Understanding of higher-level relationships within Ophiuroidea has been aided by multilocus nuclear data and ...

Transcriptome pyrosequencing of the Antarctic brittle star Ophionotus victoriae
Marine Genomics, 2013Brittle stars are included within a whole range of species, which contribute to knowledge in the medically important area of tissue regeneration. All brittle stars regenerate lose limbs, but the rate at which this occurs is highly variable and species-specific.

Development of the nervous system in the brittle star Amphipholis kochii
Development Genes and Evolution, 2007There 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 extent of similarity of neuroanatomy and neural development in the ophiuroids with other echinoderm larvae, we investigated the development of the nervous system ...

The behaviour of some amphiur1d Brittle-Stars
Journal of Experimental Marine Biology and Ecology, 1975Abstract Eight species of burrowing amphiurid brittle-stars have been observed in small aquaria. Burrowing is effected by the tube-feet and the arms; the animals come to lie in a semi-permanent burrow whose walls are reinforced with mucus, in such a way that the disk is several centimetres down but the tips of the arms can explore the surrounding ...

The Propagation of Star-Shaped Brittle Cracks
Journal of Applied Mechanics, 2010The paper studies the dynamical propagation of star-shaped cracks symmetrically arranged in an elastic thin plate, subjected to the action of instantly applied, comprehensively (uniformly) stretching stresses, which implies a self-similar problem with homogeneous stresses and velocities of particles.

Spawning behaviors of two congeneric brittle stars
Marine Ecology Progress Series, 2009Broadcasting gametes for external fertilization is a common reproductive strategy of many marine invertebrates; however, little is known about adult behaviors because of the brevity and unpredictability of spawning. We studied the spawning of 2 shallow-water brittle stars — the subtidal Ophiocoma dentata and the intertidal O.

Curacin E from the Brittle Star Ophiocoma scolopendrina
Journal of Natural Products, 2016Bioassay-guided fractionation of the extract of the brittle star Ophiocoma scolopendrina afforded curacin E (1), a congener of curacin A (2). Curacin A (2) is an antimitotic agent of cyanobacterial origin. The structure of curacin E was studied by interpretation of NMR data and the ECD spectrum. Curacin E has an ethylcarbonyl terminus in its side chain

The Possibility of Paralytic Effects of Selected Sea Stars and Brittle-Stars on Octopus Bimaculatus
Transactions of the Kansas Academy of Science (1903-), 1964Lane (1962, pp. 66-67) mentions that sea stars (Asteroidea) and brittle-stars (Ophiuroidea) may be dangerous to octopi, citing field observations by Schmitt and Voss. In Alaskan waters, Schmitt saw an octopus (species not mentioned) that had been slithering across a ship's deck immobilized by having several starfish (species not mentioned) thrown on it.
