a marine invertebrate with a body full of holes through which water can circulate and nutrients can be absorbed
What is a "sponge"?
A sponge is a simple multicellular organism that belongs to the phylum Porifera. They are characterized by their porous body structure, which is made up of numerous tiny openings called pores. Sponges can be found in a variety of marine environments, from shallow coastal waters to the depths of the ocean. They have a remarkable ability to filter water and extract nutrients from it using specialized cells called choanocytes. Sponges come in a wide range of sizes, shapes, and colors, with some species forming intricate and beautiful structures. They play important ecological roles by providing habitats and serving as filter feeders, helping to maintain water quality and biodiversity. Despite their seemingly simple appearance, sponges possess unique biological features and are a fascinating group of organisms in the marine ecosystem.

a porous material used by artists to apply and blend paints by soaking up paint and releasing it onto a surface
What is a "sponge"?
A sponge is a useful tool for applying and manipulating paint or other materials. Artists use natural or artificial sponges to create textures, blend colors, and add effects to their work. Sponges can be used for various techniques to produce unique patterns and textures. They are particularly helpful for creating softer, more natural effects and for applying washes or glazes. Sponges come in different shapes, densities, and sizes, allowing artists to achieve a range of artistic effects depending on their needs.
