Species: includes Harmothoe lunulata, Lepidonotus sp., Harmothoë sp., and Lagisca sp. Physics Application(s) Overview: Bioluminescence Species
distinctions: Scale Worm:
Habits, physical and social structures: The free-swimming scale worm is also known as a bristle worm, brown, fuzzy in appearance and covered with a double row of oval-shaped scales which protect its body like an armour. They may be observed among brown and green seaweed or on the mud along the coasts of western Europe. In the Harmothoe lunulata, the males are separate from the females where the gametes detach from the gonads and float in the coelum until they are mature. Once fertilized in the water, the eggs develop into free-swimming larvae, which sink to the bottom of the water and turn into adults. Physics Application(s): Bioluminescence: Although bioelectricity plays a role in the survival of the scale worm internally, bioluminescence is what it is known for. When subjected to particular conditions involving mechanical, chemical, thermal, or electrical stimuli, the scales of the worm instantly emits flashes of green or blue light at one to nine flashes per minute, in no particular pattern. An interesting property of the organism, like in many worms, is that even when severed into many pieces, the scale worm retains the ability to generate light within their body, due to the fact that the body of the worm consists of many similar subunits.
