Here's what I've just learned when taking a one-hour marine class at the Loggerhead museum in Juno Beach, Florida:
Mullusks (which are snails, slugs, mussels and even octopuses which can be as small as 3-inches!) prey on other species of shells by "drilling" with their mouth-parts. After their puncture, they insert that part into the shell-victim's body, and well, such is the eco-system.
Only today did I collect about 20 of such shells to bring back to Massachusetts for friends who may wish to wear these beach jewels around their neck.

They have small holes in their shells.
The lizards live in these holes and Mr.Sir left sunflower seed shells in these holes and the lizards eat these shells for food.

Well it may happen naturally or someone or something put holes in it.Hope this helps :)
Piercing tools pierce holes in previously blanked,formed or drawn parts.It is often impractical to pierce holes while forming because they would become distorted in the forming operation.In such cases they are pierced in a piercing tool after forming.
Oyster drills
The Mohawk Indians made their money from shells or cockles that they found on the beach. They would drill holes in the middle of these little bones and attach them to string.
