But what is the real nature of sea sponges? Believe it or not the sea sponges belong to the animal kingdom! They are ANIMALS (invertebrate)!!
Sea sponges are of course of the simplest form of multi-cellular animals. They live in deep seas attaching themselves to the sea bottom and in locations rich of food for them.
Sponges found in the Mediterannean Sea are considered of the best quality, followed by the Red Sea sponges and the West Indian sponges. Sponges of lower quality can be found throughout the world’s seas and also in freshwaters.
The sponges are of high quality when their skeleton is composed of a soft, flexible, yet durable substance (the sponging tissue) and at the same time they contain no hard spicules.
The natural soft bath sponge, is actually the skeleton of these living sponges. The living tissue is dried, washed and bleached resulting in the soft, smooth, flexible, absorbent sponge that many of us enjoy to use in our bathrooms (and households).
