In the videos above and below you see the Electric Flame Scallop, also called the Disco Scallop. Technically its not a scallop. Its not in the same family (Pectinidae) or even Order (Osteroida). Nope this guy or gal is the family Limoida in order Limoida. They are about as different to one another as a bat to whale (also in different taxonomic orders). Of course, I’m just pissy because I study mollusks. The real reason I posted, and not just to bitch, is that because of the spectacular
UPDATE: Lindsey Dougherty commented below. Lindsey is graduate student at the University of California, Berkeley whose research I completely missed when I wrote this. As she mentions below in the comments, the species is actually Ctenoides ales. Lindsey presented work recently at the Society of Integrative and Comparative Biology meeting both determining the evolutionary relationships of this unique bivalve but how it generates light. As she mentions in her abstract, these are the only known bivalves with a light display. These critters actually ARE NOT BIOLUMINESCENT. Part of their mantle is actually iridescent and the clam actually furls and unfurls the reflective bits to cause the light show. Pretty cool stuff and sorry to Lindsey.
