Amalda australis explained

Amalda australis, common name the southern olive, is a medium-sized sea snail, a gastropod mollusc of the family Ancillariidae.^[1] These predatory snails live in the inter-tidal sand,^[2] an environment that lends itself to high probability of fossilization.^[3] Amalda australis fossils date back to the Pliocene and reveal morphological stasis.^[4]

Distribution
