Vermeij, 1993). The present study documents how hydrodynamic forces actually vary with the shape of limpet-like models and uses these data to explore the potential of hydrodynamic forces to serve as a selective factor in the evolution of shell shape in limpets.

Despite the extreme severity of this flow environment, predictions from conical models suggest that limpets' shells are typically far from the optimal shape that would minimize the risk of dislodgment, a deviation that is allowed by the high tenacity of the limpets' adhesive system.

Limpets are marine gastropods that live on rocky coasts and in tide pools. ... The shape of a limpet's shell has a great deal to do with whether the animal remains securely attached to its rock or is ripped off and thrown onto dry land or into the waiting tentacles of a hungry sea anemone. There are two ways a wave can...

Title: Investigation into the shapes of limpets on sheltered and exposed rocky shores. Aim: The objective of this investigation is to determine whether there is any statistically significant difference between the dimensions, or shape, of limpets on sheltered and exposed rocky shores.

Limpets are robust their cone shape shell is structurally strong, not many predators are capable of breaching this defence. Their conical shape means that there is a large surface area in contact with the rockface.

The shells of the true limpets in NSW vary widely in shape and colour. Unworn, adult shells of the larger species can usually be identified, but it is almost impossible to identify worn shells, particularly juveniles, and the smaller species.

Molluscs - Limpets ... To make matters worse, environmental conditions can also affect size, shape, ornamentation and colour, so that members of a single species may look quite different to one another.
