Ribbed Limpet

Lottia digitalis

The Ribbed limpet commonly occupies rocky intertidal zones and it is the major site of larval development (1). There are two morphological types with the base shell color either being white with dark stripes or an overall dark color; the surface in which it adheres to greatly influences the color (2). Barnacles are a common host and there is a correlation with the color and habitat it occupies since darker limpets adapt their color to match their environment for survivability and decrease predation (2.) This species also adapts to fluctuations in temperature determined by the rock they occupy, making them model organisms to study the effects of climate change by directly measuring their metabolic own activity (1).
