The major function of spicule is to provide structural support to the organisms. Spicules also play other roles and one of the roles is to provide deterrence from predators that might attack.
A spicule provides support and structure to a sponge. It is a part of the sponge's skeleton and helps to fight off predators.
spicule other than support secrets the chemical that on coming in contact with air solidifies and becomes the web in spider.
Spicules provide structural support.
Spicules are tiny structures of hard crystal that give the sponge it's shape. There are many different types of spicules, some examples are; acanthostyles, stongyles, and anatriaenes.
spongin is the soft material that makes up a sponge´s skeleton and spicule provides support for the sponge.

Spicules, most commonly found in the Phylum Porifera (sea sponges) provide support for the animal and defense against predators. Some studies have also been conducted that prove spicules to sort of act as light transmitting features on deep sea sponges.
Spicules provide structural support.
Spicules provide support to the sponge. In fact, a spicule is defined as any (of various shapes and sizes, depending of the sponge) small calcareous or siliceous body embedded along the sponge's cells.
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
Cnidarians do not have spicules. Spicules are commonly found in sponges and it is a simply a skeleton which has very tiny splinters that look like needles.
Sponges have collar cells, osculum, and spicules.
Sponges have collar cells, osculum, and spicules.
Sponges have collar cells, osculum, and spicules.
it is scleroblast cells which produce spicules which are modified amoebocytes
Sponges have collar cells, osculum, and spicules.
calcarea - have calcite spicules, often have calcite exoskeletons glass sponges - silica spicules, no exoskeleton demosponges - silica spicules, may have exoskeleton, made of aragonite if present
Spicules travel at about 20 km/s (72,000 km/h, 45,000 mph)
