Nodilittorina pyramidalis, commonly known as a Pyramid Periwinkle, is a species of sea snail, a marine gastropod mollusk in the family Littorinidae, the winkles or periwinkles.[1]


The Pyramid Periwinkle is small, ranging from 2.5 cm to less than 1 cm in length. It is pale grey in colour, with two rows of nodules on the central whirl of its body which are a pale buff colour. It lives on or above the high tide line, usually clinging to vertical surfaces. Many individuals will cluster together in crevices to maintain moisture.


Pyramid Periwinkle are endemic to Australia and can be found in abundance on both the east and west coasts.
