Sinistral ancient neptune: red whelk: buckie

When viewed from the top whelk shells normally spiral in a clockwise direction. This is known as dextral or ‘right handed’. Very rarely a mutation produces snails whose shells coil anticlockwise - they are known as sinistral or ‘left-handed’.

It’s not just the shell of a sinistral whelk that is a mirror image of the more common dextral form; it’s internal organs are on the opposite side too. For molluscs this makes mating very challenging.
