Amalda mucronata

Amalda mucronata is a species of medium-sized sea snail, a marine gastropod mollusc in the family Olividae, the olives[1]. These snails live in the sandy subtidal near-shore environment where they eat bivalves. Fossil material of this species provides evidence of morphological stasis over 5 million years[2][3]

gollark: Nope. Just disassemble asteroids into gold and other rare metals.
gollark: Sure, there's a spectrum of difficulty of making more.
gollark: It's also just something people agree is shiny and expensive™, but it's been shiny and expensive™ longer.
gollark: Gold isn't "inherently valuable" either.
gollark: It is basically baked in increasing inequality.
