We have a conundrum, a puzzle and even a bit of an oddity. As you know the Mom has been collecting some shells and in particular she loves these 'shark eye' shells but so far every single one of them she has found has had ONE perfectly drilled hole in the side of it. Now the conundrum is what is doing and why?
You can tell from the hole that is been drilled from the outside in - was something trying to get to the mollusk inside - but why not just go directly through the big opening on the bottom that each has? Was King Neptune planning to make a necklace with them? Is there some deranged fishy with a drill bit for a nose?
Now lets see how creative you can get at providing an answer for this conundrum :) And if you can't guess - we found the answer - it is below the photos :)
The smooth, gray to tan spherical shark eye shell is one of the prettiest found on the Atlantic coast measuring 1/4 to five inches in diameter. These predators feed on other mollusks, especially clams, by drilling a hole with its radula through the shell and at the same time secreting an acidic substance that softens the shell. After completing a perfectly beveled hole, this snail will suck out the body of the mollusk eating up to four clams a day using this method. Moon Snails will actively hunt for their food and will consume other Sea Snails, Sea Stars, Oyster, Fish and will even prey upon each other !
