Spicules are the defensive structures in sponges which are needle like. Special fringes and pallisades of spicules guard the apertures to prevent the entry of intruders.
Sponges not only have spicules to defend but also have other mechanisms to defend their enemies.
some produce unpleasant odour and some produce poisonous substances. These poisonous substances when handled cause irritation of the skin and have strong oxidizing action and some may be fatal.
