A member of the Roseobacter clade, Octadecabacter sp., is the dominant symbiont in the brittle star Amphipholis squamata [PDF]
FEMS Microbiology Ecology, 2018 Symbiotic associations with subcuticular bacteria (SCB) have been identified and studied in many echinoderms, including the SCB of the brooding brittle star, Amphipholis squamata. Previous studies on the SCB of A. squamata placed the isolated bacterium, designated as AS1, in the genus Vibrio (Gammaproteobacteria), but subsequent studies suggested that ...

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.

Evidence of seasonal variation in bioluminescence of Amphipholis squamata (Ophiuroidea, Echinodermata): effects of environmental factors [PDF]
Journal of Experimental Marine Biology and Ecology, 2000 The bioluminescence of Amphipholis squamata was assessed from freshly collected individuals for 16 successive months, and from individuals maintained in the laboratory under various experimental conditions of salinity, temperature and photoperiodic regime.

Amphipholis squamata is a small ophiuroid considered to be distributed worldwide except in Polar Regions. Numerous colour varieties were reported fur this species, which is also bioluminescent. It is hermaphrodite and brood protecting; both selfing and outcrossing occur.

Luminescence control in the brittlestar Amphipholis squamata: Effect of cholinergic drugs
Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1996Potassium chloride and cholinergic drugs were rested on isolated arms of Amphipholis squamata; potassium chloride triggered a monophasic light emission; acetylcholine (10(-3) M) induced a luminescent response characterized by multiple flashes. ACh luminescence was increased in the presence of the cholinesterase inhibitor, eserine. Nicotinic antagonists,
