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.


Sponges primarily use chemicals to protect themselves, and the chemicals are either toxic or just taste bad. This not only prevents predation but also competition, as the chemicals they release prevent other organisms from growing near them. Individual species have other strategies, such as burrowin


The amount of water a sponge can absorb depends on many factors. The material the sponge is made out of, the structure of the sponge and the size of the sponge all affect how much water the sponge can absorb.


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.


Sponges are extremely slow-moving or sessile filter-feeders that draw water through pores and specialized filter cells to gather food. Sponges are the most primitive type of animal in existence, featuring a cell-based organization where different cells have different tasks, but do not form tissues.


Depending on the sponge, food is obtained through filtering water for nutrient-rich particles or snaring small sea creatures with specially adapted arms. Most sponges are detritivorous, consuming debris particles and microscopic life forms that float their way.


The sponge's adaptations include being an excellent filter feeder. Because a sponge is sessile, its body is full of pores that allow water rich with nutrients such as plankton to enter its body cavity. Once there, the plankton is filtered out, and the water is expelled.


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.


Sponges continually pump water through the ostea into an internal system of canals and expel it from the osculum, trapping food and removing oxygen from the water. They use collar cells in these canals to flip flagella, creating the pumping action that forces the water through their structure and tr


German scientist Otto Bayer, who founded the Bayer Company, was the inventor of polyurethane foam, the material from which sponges are made. Bayer invented this material by accident in 1937.
