Poseidon is a Japanese rock oyster. Rock oysters grow in the deep sea, about 20 meters below the subtidal zone. Their shell is important to protect them from predators. Yes, there is a sense of volume. Summer is the season. Rock oysters can only be eaten raw in areas with clean seawater rich in nutrients from the mountains. Poseidon is farmed in a naturally blessed environment, so you can safely eat it even if it's alive. Rock oysters come in both wild and farmed varieties, but most are wild. Wild oysters have a taste similar to real oysters, but cultured rock oysters, which are systematically raised, have plump flesh and a stable taste. Rock oysters grow slowly over a period of 3 to 5 years before being shipped.
