Acmaea juanina is a species of sea snail or true limpet, a marine gastropod mollusc in the family Acmaeidae, one of the families of true limpets.[1]

Description

[edit]

(Original description) The ovate shell is of moderate height with its apex in the first third of its length. The anterior and lateral slopes are straight, the posterior one a little convex.

The sculpture consists of concentric striae and radiating ribs of alternating strength, 11 principal ones with finer ones in the interstices. The coarsest ribs (4 in front, I on each side and 5 behind the apex) as well as the apex are dark-violet in colour, olive-brown towards the periphery like the intervening ribs. The ground is white. The interior of the shell is white, with a chestnut centre and an olive-green margin.[2]

Distribution

[edit]

This marine species occurs in the Pacific Ocean off Juan Fernandez and Desventuradas, Chile.
