They're also known to glow in the dark, a bioluminescent characteristic that gives the organism its scientific name: pyrosoma, Greek for "fire body."Pyrosomes have rarely if ever been seen along the US West Coast until 2012, when first spotted in California waters. Since then, they have gradually multiplied and spread north, before exploding in numbers this spring, according to scientists with the National Oceanic and Atmospheric Administration.Although harmless to humans, they have been especially troublesome to the commercial salmon catch in Oregon, with large globs of the rubbery critters clogging fishing gear by the thousands in recent months. Some have even washed ashore.
