Any one of numerous species of Spongiæ, or Porifera. See Illust. and Note under Spongiæ.
The elastic fibrous skeleton of many species of horny Spongiæ (Keratosa), used for many purposes, especially the varieties of the genus Spongia. The most valuable sponges are found in the Mediterranean and the Red Sea, and on the coasts of Florida and the West Indies.
a sea animal that has a rubbery skeleton with many holes that absorb water.
Simple animals which look like sponges under water, covered in small openings
a porous mass of interlacing fibers the forms the internal skeleton of various marine animals and usable to absorb water or any porous rubber or cellulose product similarly used
primitive multicellular marine animal whose porous body is supported by a fibrous skeletal framework; usually occurs in sessile colonies
gather sponges, in the ocean
an animal that lives in the ocean
a primitive animal that lives in the water
a primitive coalition of protozoa with enhanced survival over any one protozoan
a simple invertebrate animal that is a member of the phylum "porifera
a simple invertebrate animal under the classification of the phylum porifera
a simple organism that is easy to describe
any of a phylum (Porifera) of aquatic lower invertebrate animals that are essentially double-walled cell colonies and are permanently attached as adults.
A permanently attached animal having a soft, porous skeleton and being of various sizes, shapes and colours.
n. Phylum Porifera. A group of organisms at the base of the animal kingdom, characterized by a cellular level of organization and flagellated cells that capture tiny microscopic food the size of bacteria.
Animals of the phylum Porifera, the most simple form of multicellular animal life. Some sponge species function as shelter for fishes and crab.
A sponge is a tool consisting of porous plastic used for cleaning impervious surfaces. Sponges are especially good absorbers of water and water-based solutions. Because many sponges are used in kitchens, they can harbor dangerous bacteria.
