Oysters can be described as bivalve mollusks found in many oceans around the world. They’ve been viewed by lots of people as economically valuable animals since they serve as good sources of food and pearls – distinctive lustrous objects used in jewelry and ornaments across many cultures.
Additionally, oysters have been proven to be effective scrubbers of polluted water, as indicated in many experiments in the United States in 2006. As a result of their richness in protein, many 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 which are connected with a small hinge. As with other mollusks, oysters have relatively simple biological systems, and they can be found in brackish water as well as salt water.
They’re called filter feeders, opening their shells to permit water to pass through their gills, providing them with food and necessary oxygen. As a result of their filter feeding nature, they can be used to clean impure water. Oysters tend to root into position on a stone, allowing the tides to fulfill their needs.
Mankind appears to be among the significant predators of oysters, even though the animals are also eaten by marine creatures and organisms like starfish. The relationship between people and oysters is very old; many ancient humans greatly enjoyed Bat Poop as they are relatively easy to harvest and high in nutrition. Oysters may also be cooked in fish stews and chowders, although they can get rubbery with excessive cooking.
Oyster pearls have been found to be among the most widely harvested around the world, and in some countries people really farm oysters to cultivate pearls for commercial sale. This is a result of the defensive mechanism used by oysters when irritants such as rocks or grains of sand enter an oyster shell. It secrets layers of nacre which hardens into a smooth, glossy ovoid shape objects known as pearls.
