Geometric Cowrie

Guardians: Emily Tam & Gallant Lee
Mauritia arabica

Most snails have a lid or a door to shut up their shell. The cowries have a made their opening long and thin to stop predators and they have added ridges along the opening to make it stronger. The opening is usually curved so that it looks like a smile but no-one can explain this, perhaps cowries have found the secret to happiness.
