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.
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.
The scientific name of the sea sponge is Porifera. The sea sponge's scientific name refers to something having pores, and sea sponges have many small pores known as ostia.
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
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.
Sea sponges reproduce asexually by budding and sexually by releasing male gametes into the water. These gametes are taken in by other sponges, which then produce blastulas that are also released into the water. Budding can be external or internal. Internal budding is reserved for harsh conditions, i
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
Sponges filter food particles out of the water by forcing the water through their porous bodies with a self-generated miniature current, which brings particles within reach of the walls of their pores where cells absorb them. Sponges are complex organisms whose cells perform many different tasks suc
