Up close, it could be imagined like a desert patriot doing business under the sand. Obviously I don't know what to look for under the sand, but it's fun to watch it burrow the sand.
In fact, the sand burrower really doesn't like being on sand, let alone dry sand. I took it to the sand which was dry, waterless, it barely moved, or maybe it got really scared!😁
But when I brought it back to the sand soaked by sea water, it reacted again. It ejected its body again and immediately covered itself in sand, flipped its long aperture downwards, and began moving with its bullet-like shell to burrow the sand until it disappeared beneath the sand.
Of course it doesn't like dry sand because it is a marine gastropod mollusks or sea snail. There are actually very many sand burrower snails and they are known as Family Mitridae, but about this one, although it is similar to mitrids, it belongs to the family Pleioptygmatidae (J.F. Quinn, 1989), and it is said that Pleioptygma helenae is the only extant species in the family.
I once found a shell very similar to this sea snail shell on a hill with other coral fossils. Is it the ancestor of this snail or maybe it is another species that became extinct millions of years ago? However, it is also amazing when the fossil of the sea snail shell was not only found in a dry place, but also very high above sea level!
