Amalda australis

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].

gollark: Hmm yes, I too enjoy interacting with friends while frying my brain and liver somewhat.
gollark: Alcohol bad (although people should be allowed to use it still, obviously, if they find it fun or something).
gollark: For *basically everyone*, it does muck with reflexes and decision making.
