Why Do Shells Have Perfect Holes In Them. These shells are from bivalves, which are marine snails that instead of having the spiral shell we associate with snails, have two dish like shells called valves. Ever found a shell on the beach with a perfect hole in it for a necklace? The snail can fully withdraw itself between the two shells and close them tightly to avoid predators. The shell to the right with a hole through it was hinged to another shell of equal size with an animal living inside (in this case, a clam). The hole in this sharks eye tells me a little secret of what happened to its life. It has a perfect countersunk borehole with a beveled edge twice the diameter as the inner diameter. Omnivores, such as dog whelks and moon snails, use their radula to “drill” a hole in its prey, then uses its proboscis to suck the contents. To get to the tasty morsel inside, whelks have evolved to use their radula (an organ like a tongue) as, essentially, a drill. We see natural holes drilled in all sorts of shells, so it’s time to find out how they are made. Visually striking markings can be used to attract a mate or provide camouflage, but elaborately decorated clams and mussels can spend their entire lives unseen, hidden under a rock or buried in sand. While sea shells serve as protective homes for their fragile inhabitants, shell patterns have a less obvious purpose.
