Trochus pagodus Linnaeus, 1758 Tectarius pagodus is a species of sea snail, a marine gastropod mollusk in the family Littorinidae.

That family is commonly known as the winkles or periwinkles.

[1] This species is the largest member of the genus Tectarius, and (like the rest of the family Littorinidae) is an herbivor.

[2] This species is endemic to the Indo-Pacific.

[3] It can be found in the upper part of the intertidal zone along rocky shores, and therefore does not often get submerged.
