SPICULES Meaning and
Definition
-
Spicules are small, needle-like structures found in various biological organisms and mineral formations. Derived from the Latin word "spiculum" meaning a sharp point or splinter, spicules often serve as supportive or defensive structures.
In biology, spicules are commonly found in sponges, which are simple aquatic animals. These structures are made of either calcium carbonate or silica, and provide structural support and protection for the sponge's body. In some sponges, spicules can be easily seen protruding from their surface, while in others they are embedded within the body.
Spicules also exist in other organisms such as the echinoderms, which include sea stars and sea urchins. In these marine animals, spicules are thin, calcified structures that are usually found in the skin or spines. They provide rigidity and protection against predators.
Beyond biology, spicules can also refer to needle-like crystals or mineral formations found in geological and astronomical contexts. In astronomy, solar or stellar spicules are dynamic jets of gas that rise from the surface of the Sun or other stars, resembling thin spikes. In geology, spicules can refer to small, elongated mineral formations that are often found in volcanic glass or certain metamorphic rocks.
Overall, spicules are defined as small, needle-like structures found in organisms or minerals, serving to provide support, protection, or characteristic features within various natural contexts.
