Oysters are one of the most bivalve species. Like their relatives the mussels have two oyster shells, seemingly impervious, like a lock to knit together. The strong muscles, protects the delicate flesh from the outside world. Oysters mainly inhabit shallow coastal waters where they live in large groups, called oyster desks (tables) or oyster Slapy. Nowadays most of these colonies are artificially generated, and only very rarely occur as a natural phenomenon.
Oysters are androgynous creatures, and despite growing up as males, they become isolated females in life so they can reproduce. This is dependent on temperature and conditions in their natural environment. Only with age they grow box. These boxes are irregular with a rough surface. Oysters can live in optimal conditions 30 years.
To be suitable for eating oysters must be three years old. During the growth of oyster farms are cleaned regularly and this ensures their high quality. Oysters feed on fine particles of plankton.
