sponge Scientific  

/ spŭnj /

1. Any of numerous aquatic, chiefly marine invertebrate animals of the phylum Porifera. Sponges characteristically have a porous skeleton, usually containing an intricate system of canals, that is composed of fibrous material or siliceous or calcareous spicules. Water passing through the pores brings food to the organism. Sponges live in all depths of the sea, are sessile, and often form irregularly shaped colonies attached to an underwater surface. Sponges are considered the most primitive members of the animal kingdom, since they lack a nervous system and differentiated body tissues or organs. Adults do not have moving parts, but the larvae are free-swimming. Sponges have great regenerative capacities, with some species able to regenerate a complete adult organism from fragments as small as a single cell. Sponges first appear during the early Cambrian Period and may have evolved from protozoa.

2. Also called poriferan

3. See Note at regeneration

4. The light, fibrous, flexible, absorbent skeleton of certain of these organisms, used for bathing, cleaning, and other purposes.

5. A piece of porous plastic, rubber, cellulose, or other material, similar in absorbency to this skeleton and used for the same purposes.

Etymology

Origin of sponge

First recorded before 1000; Middle English noun sponge, spunge, spounge, Old English noun sponge, spunge, from Latin spongia, spongea, from Greek spongiā́; verb from the noun

Explanation

A sponge has holes and soaks up liquid. One kind of sponge is a water-dwelling animal with a soft body and an asymmetrical shape. But the kind of sponge you use to clean the kitchen is usually man-made. The sponge in the kitchen or bath looks a bit like the kind that grows in the ocean, porous and soft. Originally, those sponges were made from dried sea sponge, but it's more common these days for them to be manufactured. If you absorb knowledge or information easily, people may call you a sponge. And if you live off someone else's generosity, taking handouts and giving nothing in return, you sponge off of them.
