Translation of "Mollusks" in Portuguese

All the mollusks she is capturing, they're quite easy to catch, but they've got these incredibly hard shells.

Todos os moluscos que captura são fáceis de apanhar, mas têm conchas incrivelmente duras.

But some of these mollusks will only relax if that drill is precisely in the apex of the shell, on the abductor muscle.

Mas alguns destes moluscos só relaxam se a perfuração for mesmo no ápice da concha, no músculo adutor.
