These little beauties are called Pusiostoma (engina) mendicaria shells! 
 'BeeHive' snails are small stunning snails with a striped black and white pattern that resembles the pattern of a bumble bee – hence the name. They originate from the Indo-Pacific region, but can also be found in the waters of Florida.
 
This stunning nocturnal snail is unfortunately relatively shy and is only seldom seen out during the day.
Such a great addition to any collection! These also make stunning jewelry pieces! 

The shell size varies between 10 mm and 20 mm.
6 shells come in this pricing package.
