(Peron, 1804) : Pyrosome|
Phylum Chordata / Subphylum Urochordata / Class Thaliacea / Order Pyrosomatida / Family Pyrosomatidae
Like other pyrosomes, this species is brightly bioluminescent, producing an intense blue-green glow when disturbed. It may range for up to 800 vertical meters during daily migrations. While not common in Monterey Bay, Pyrosoma atlanticum is the most widespread and abundant pyrosome in temperate and tropical waters of all oceans. With its distinctive characteristics, it is unlikely to be confused with any other gelatinous visitor to California nearshore waters. The genus name (Pyrosoma) is derived from the Greek, pyros (fire) and soma (body), referring to the bright bioluminescence characteristic of this group.
