Oyster?

[dahouck]

Thanks for the info about last week's mystery 'sponge'

This week's episode...

I didn't notice this until it opened last night. I thought it was a rock but it looks like an oyster or other type of bivalve.

It's egg-shaped, 2.5 inches long (high in the pick), and striated.

Any info?

Thanks,

Derek

not sure on that, you got some cool hitchhikers though.
