Amalda mucronata is a species of medium-sized sea snail, a marine gastropod mollusc in the family Ancillariidae.^[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]

The shell height is up to 61 mm, and the width is up to 27 mm.

Distribution[edit]

This marine species is endemic to and occurs off New Zealand.^[4]
