Oysters can be described as bivalve mollusks found in several oceans around the world. They’ve been seen by lots of folks as economically valuable animals since they serve as good sources of food and pearls – identifying lustrous objects used in jewellery and decorations across many cultures.
Additionally, oysters have been found to be effective scrubbers of polluted water, as indicated in several experiments in the USA in 2006. As a result of their richness in protein, a number of other animals have also found them to be very useful.
A mollusk is a soft bodied creature which protects itself with a shell. Bivalves have two shells that are connected with a small hinge. Oysters can open their shells to take in food in addition to expel waste substances in their systems, and they can close their shells if threatened by predators. Like other mollusks, oysters have relatively simple biological systems, and they may be found in brackish water in addition to salt water.
They are called filter feeders, opening their shells to allow water to pass through their gills, providing them with food and necessary oxygen. Due to their filter feeding temperament, they can be used to wash impure water. Oysters tend to root into place on a stone, letting the tides to satisfy their needs.
Mankind is apparently among the significant predators of oysters, although the creatures are also eaten by marine creatures and organisms like starfish. The connection between humans and oysters is quite old; many early humans greatly enjoyed oysters since they are relatively easy to harvest and high in nutrition. Some people regard oysters as delicacy, and raw oysters are often eaten for their supposedly aphrodisiac quality. Oysters may also be cooked in seafood stews, Bat Poop and chowders, even though they can get rubbery with excessive ingestion.
Oyster pearls are found to be among the most frequently harvested around the world, and in some countries people actually farm trinkets to cultivate pearls for commercial sale. This is a result of the defensive mechanism employed by oysters when irritants such as stones or grains of sand input an oyster shell. It secrets layers of nacre which hardens into a smooth, glossy ovoid shape objects called pearls.
