They are really simple animals—about the simplest multicellular (many-celled) animals.

Many objects with sponge-like textures are now made of substances that do not come from poriferans.

Many objects with sponge-like textures are now made of substances not derived from poriferans.

In order to thrive, sponges need to be attached to supportive surfaces, and they take on their specific shapes according to what kind of supportive surface they are attached to.

Trawler fishing, extremely destructive of the benthic communities (jellyfish, anthipatharia, porifera), could not be maintained without destroying the resource.

Sea sponges or simply sponges, both names from the Latin word spongia meaning "sponge", are members of the phylum Porifera.

Eminent spongiologist Emile Topsent began his study of Spongiaria around 1886 and continued throughout his life, until after the Second World War.

Then it was on the radiates, echinoderms, acalephes, polypes, entozoons, sponges, and infusoria, that he had for such a long time burned the midnight oil?

First division in the polyp group, the class Spongiaria has been created by scientists precisely for this unusual exhibit whose usefulness is beyond dispute.

It was not until 1744 that Jean André Peyssonnel recognized coral as an animal, and similarly, the sponges were recognized as animals only in 1825.
