Definitions for "Spicule"
A minute, slender granule, or point.
Any small calcareous or siliceous body found in the tissues of various invertebrate animals, especially in sponges and in most Alcyonaria.
A structural component of the chromosphere that erupts like a plasma geyser driven by dense magnetic fields. Spicules rise between 3,000 and 10,000 kilometers above the magnetic mesh beneath. At the boundary between the photosphere and chromosphere, spicules look like peach fuzz. Spicules live short, dynamic lives of a few minutes but spew plasma at speeds of more than ten kilometers a second.
