Sea sponges are bottom-dwelling, multi-cellular animals. Most sea sponges attach themselves to the ocean floor, other sea animals or rocks for the duration of their lives. A small number of sea sponges are mobile creatures that move along the ocean floor at the rate of 1 to 3 millimeters per day.
Marine animals, such as hawksbill sea turtles, angelfish, sea slugs, some starfish and the larvae of sponge-flies, feed on sponges. Not many marine animals eat sponges, because multicellular organisms contain less nutrients, are tough to eat and produce chemical toxins as their form of defense.
Sponges used for cleaning are made of either artificial or natural fibers. Artificially produced sponges are made of cellulose fiber or melamine fiber, while natural sponges are made from underwater animals also called sponges or from gourds known as loofahs. Most sponges in use as of 2014 are artif
Most sea sponges are detrivorous, meaning they consume organic debris and various microbes that drift through ocean currents. Harp sponges, however, are carnivorous and use hooks located on their arms to catch shrimp and other small animals.
Three examples of sponges are the calcareous sponges, glass sponges and demospongiae. These all fall under the main category of porifera, the scientific name for sponges.
Sponges are important because of their roles in recycling nutrients and the part they play in the coral reef life cycle. For instance, sponges break down complex organic material into food for other things living on the coral reefs.
Sea sponges are animals that live on the ocean floor. After human beings harvest and dry them, the sponges serve as the household tool many people use to bathe and wash dishes and cars, among other items.
To clean a sponge, soak it in a solution of bleach and water for five minutes. You can also soak the sponge in water and then microwave it on high for one to tow minutes. Alternatively, wash the sponge in a dishwasher on the "heated dry" setting.
The average lifespan of a sponge is 10 years or less. Sponges living in a temperate region may not live past a few years, but those living in the deep ocean may live to be 200 years old.
Many types of sponges exist within the animal kingdom, including the black-ball sponge, boring sponge, branching tube sponge, giant barrel and green finger sponges, and many more. Sponges live primarily in aquatic environments, and they are found on ocean floors around the world. They vary in size a
