Nassarius snail sand cleaner

The aquarium clean-up crew Nassarius snail species typically do not reach mnassarius-2uch more than a half inch of length. Despite their small size, they have a relatively rugged shell. The shell is spiral in shape (with a nice sharp spire, in fact) with a nice rugged outer texture. Tan, beige and brown bands run along the width of the shell. Nassarius snail shells are a bit variable in texture and color pattern, but can be quite beautiful and have been used by humans as jewelry for many thousands of years. So, even though these creatures fulfill an important duty as cleaners, they can also be attractive display animals.
