Abstract

The fresh-water sponges were observed but not recognized as animals at a very early period. The early investigators thought they were plants; later workers, colonial protozoa. In 1696, Leonard Plukenet first made public mention of them; and later, in i745, Linnaeus described them as Spongia and made mention of their, "globuli". After Linnaeus the term Spongia changed many times until, in 1816, Lamarck introduced the generic name Spongilla.
