How to identify Pacific oyster?
Natural distribution & biology Pacific Oysters have a thin shell, with no hinge teeth inside the upper shell (unlike Sydney Rock Oysters). The adductor muscle (which holds the two shells together) is purple or brown in colour, whilst the edges of the mantle (the tissue which secretes and lines the shell) are black.
How do oysters make pearls?
To create a cultured pearl, the harvester opens the oyster shell and cuts a small slit in the mantle tissue. Small irritants are then inserted under the mantle. In freshwater cultured pearls, cutting the mantle is enough to induce the nacre secretion that produces a pearl — an irritant doesn’t have to be inserted.
What toxins are in oysters?

Can you eat pearl oysters?

Is Pacific oyster an invasive species?

Why are Pacific oysters invasive?
Although this species has been introduced worldwide, it is considered an invasive species as it outcompetes native species for space and food. Oysters are threatened by ocean acidification, habitat destruction, and pollution. Ocean acidification inhibits an oyster’s ability to form a shell.
Are Blue Point oysters safe to eat?
