You see, the sea is a wonderful powerful thing. It have the ability to carve anything, no matter how hard it is... just give it lots of years to do it, it will do a wonderful job! This shell was once the house of a cobito (a tiny hermit crab) and after many years of getting "caressed" by the waves it got this fossil style shape.
I have no idea how many years it took for this shell to end up like this... 10? 25? 100? Way more than 100 years? It was polished, soft to the touch, very light and flattened. It has lost long ago its original shape and the opening where the little hermit crab use to came out. It has lost its original color too, now it looks kind of pale pink... I think the original color was reddish brown like most of cobitos here. Is the first time I found a shell like this. Most of the time they are broken or empty but not shaped into this thanks to the salty sea water. It was an interesting finding! A reminder that with time anything is possible. Time and effort can shape the hardest things... and that is a fact!
