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 because 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 many experiments in the United States in 2006. Due to their richness in protein, a number of other animals have also found them to be very helpful.
Bivalves have two shells which are connected with a small hinge. Like other mollusks, oysters have relatively simple biological systems, and they can be found in brackish water as well as salt water.
Oysters belong to the family Ostreidae. They’re called filter feeders, opening their shells to permit water to pass through their gills, supplying them with food and necessary oxygen. As a result of their filter feeding temperament, they may be used to clean impure water. Oysters tend to root into place on a rock, letting the tides to fulfill their needs.
Mankind is apparently among the major predators of oysters, even though the animals are also eaten by marine animals and organisms such as starfish. The connection between humans and oysters is quite old; many ancient humans greatly enjoyed oysters since they are relatively easy to harvest and high in nutrition. Some people regard oysters as delicacy, and raw shellfish are often eaten for their supposedly aphrodisiac quality. Oysters may also be cooked in seafood stews, Bat Poop and chowders, although they can get rubbery with excessive cooking.
Oyster pearls are found to be among the most widely harvested around the world, and in some countries people actually farm oysters to cultivate pearls for commercial sale. This is a result of the defensive mechanism used by oysters when irritants such as stones or grains of sand input an oyster shell. It secrets layers of nacre which hardens to a smooth, glossy ovoid shape objects called pearls.
