Based on your religion, you may be told that any nonbelievers will go to a bad place; Hell, the Underworld, left to roam the world of the living never to pass on to the next life, etc. As an Evolutionist or Atheist, I don't know what happens to me when I die. I belive my body will remain on this earth (unless I get my body shipped off world into space for disposal lol), while my mind and conciousness fades away.
Answer:
Description below
Explanation:
Alcionaceans (Alcyonacea) is an order of corals that belongs to the subclass Octocorallia, of the Anthozoa class. <em>Soft corals</em> are commonly called, since they do not produce skeletons of calcium carbonate, so they do not contribute to the construction of the reefs, although they inhabit them.
The so-called soft corals and leather or leather corals, mostly meaty in appearance, have microscopic crystals of calcite in their tissues called spicules, whose function is to give consistency to the animal's tissue, in the absence of a skeleton. The shape and distribution of the spicules are the main characteristics used in the identification of genera and species of octocorals.
In addition to soft corals, this order includes gorgonians, which replace the skeleton of hard corals, Scleractinia order, by semi-rigid structures composed of calcite and / or a substance they generate called gorgonin.
