One of the most obvious differences between Cowries and False Cowries is that Cowry shells are very round whereas False Cowry shells are frequently more elongated...
Still, they only reach about 6 cm (2.4 in) long at most so we should be safe.
Spindle Cowries climb about the branches of soft corals and gorgonians...

Just to add insult to injury, some of them can also acquire pigments and colour from their food! It doesn't affect their shell, but that's no trouble for a False Cowry since the newly coloured flesh of their mantle can completely cover it.
