It is considered to be the most resistant out of all the sponge species. Its origin is the Mediterranean Sea (the Aegean Sea and the North Coast of Africa). The best quality elephant ears are fished in South Italy.
Its appearance is similar to Silk, but it is thinner.
Due to its durability, it is mainly used for industrial use, abrasion and cleaning of surfaces like leather, glass, porcelain, pottery etc. Most of these sponges are perfectly rounded, by nature, and look like funnels or hats and consequently are used as decorative elements.
Most of the buyers prefer it in its natural brown color.
