Journal of Experimental Biology, 1999 Amphipholis squamata is a polychromatic luminescent ophiuroid. The effects of amino acids ( &ggr; -aminobutyric acid, GABA, taurine, glycine and glutamate), N-methyl-d-aspartate (NMDA) and the invertebrate neuropeptides Antho-RFamide, FMRFamide and ...

Journal of Experimental Biology, 2000 The effects of catecholamines (dopamine, adrenaline, noradrenaline and its derivatives), 5-hydroxytryptamine and purines (adenosine, ATP and their derivatives) on the acetylcholine-induced luminescence of isolated arms and dissociated photocytes of the ...

Invertebrate Biology, 2009 The ophiuroid Amphipholis kochii is able to detach its central disc from the underlyingoral frame in response to external stimuli. In this article we supply new observationson the microanatomy and ultrastructure of the autotomy plane, and of the ...

Cell and Tissue Research, 2000 Bioluminescence in the ophiuroid Amphipholis squamata is produced by photocytes located within the spinal ganglia of arm spines. Ganglionic cells were dissociated (pronase digestion) and photocytes separated from other cell types by using a continuous ...

The ultrastructure of the cuticle, fibrillar glands and stäbchen (see Reichensperger 1908) of the arm spines of the brittle star Amphipholis squamata are described. Stäbchen are shown to be cuticular projections into which pass one or more uniciliate cytoplasmic processes.

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 ...

Morphology of the juxtaligamental system in the ophiuroid Amphipholis kochii
2009Book abstract: Echinodermata have a rich fossil record, play major ecological roles in marine benthic communities from the intertidal to the deep sea, have economic importance in fisheries and aquaculture, show unique biological characteristics and have become important models in biomedical research.
