Sep 3, 2008: Huge Oyster

This oyster was so impressive Teresa had to save it for show-and-tell. What makes this oyster particularly amazing is that it was shucked in August, when our oysters are normally at their smallest. Why do some types of oysters get huge, and other's stay small? See our guide to oyster species.

Not impressed? Need a sense of scale? Look closely at the picture and you'll see an adult hand through the plastic tub. Big oyster, big shell, lots to inspect - here's a closer look at the basic parts of oyster shells.
