Luminescence control in the brittlestar Amphipholis squamata: Effect of cholinergic drugs
Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1996 Potassium 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,

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.

Netherlands Journal of Zoology, 2000 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.

Journal of the Marine Biological Association of the United Kingdom, 1997 Six colour varieties were recognized in an intertidal population ofAmphipholis squamatafrom Normandy (France). Each variety exhibits its own capacity to produce light, the light emitted by the most luminous variety being 500 times more intense than that emitted by the least luminous one.

Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 2000 Individuals of the cosmopolitan ophiuroid Amphipholis squamata were collected from eight stations. Eleven colour varieties were described and their distribution was non-random among stations. This suggests that the varieties differ in ecophysiologic tolerance and that their geographical distribution is modulated by environmental conditions.
