? Biofouling – Definition and Explanations


Tubeworms, sponges, algae, sea anemones and other organisms in the waters of Redwood City, USA.

we give a name biological pollution the contamination (a issue (Matter is the substance that makes up any body that has material reality.

This phenomenon is mainly found in marine environments where zooplankton are relatively diverse and abundant, but to a lesser extent in freshwater environments.

These are called living things epibionts. Most time (Time, by man…if the epibiont is removed from its substrate and remains intact water (Water is a ubiquitous chemical compound on Earth, essential for everyone…)it no longer attaches to the substrate and eventually dries up at the mercy of predators.

If these organisms are removed from the original substrate and remain in full water, if they are reattached to the substrate, they can attach to it and live normally.

  • Some animals, plants, and other species do not always wait to release sperm and eggs into the water, which will lead to plankton larvae that will attach to the substrate after fertilization; If this creature is broken for one reason or another, the severed “limb” will drift in the water until it attaches itself and individual (WikiDictionary is a free and open source dictionary project similar to Wikipedia (both…) separate (Or a new colony in the case of colonial animals). such as in some cnidarians coral (Coral is an animal of the phylum Cnidaria, it usually lives in colonies…) to beator certain algae such as caulerpa.
