And so what we did is we have two oysters that are stuck together, and this area used to be completely filled in with the cement, and what we're finding is that the cement has lots of different components in there, but broadly speaking, there are hard, non-sticky parts and there are soft, sticky parts, and what we did is we removed the non-sticky parts selectively to see what's left for what's actually attaching the animals, and what we got is this, and we can see there's this sticky adhesive that's holding them together.
Nós colocamos duas ostras grudadas juntas, e esta área costumava estar cheia de cola, e descobrimos que a cola tem muitos compostos diferentes, em termos gerais, há partes duras e antiaderentes e há partes moles e pegajosas. Então, removemos seletivamente as partes antiaderentes para ver o que de fato estava grudando os animais, e conseguimos isso, e podemos ver que há um adesivo pegajoso que os mantém juntos.
