It would be unable to succeed if it could not remain in its preferred habitat. Furthermore, during low tides, the tight seal that the common limpet creates with its rock prevents it from drying out in the sun.
Common limpets are herbivorous, but they likely also eat young barnacles and other things that settle on their home rocks. It is very difficult for sedentary animals or plants to become established in a common limpets territory because it scrapes its rocks clean in a relatively short period of time. Common limpets reproduce through a behavior known as broadcast spawning, where several females release eggs and several males release sperm into the water at the same time. This method increases the likelihood that eggs will become successfully fertilized and that fertilized eggs will not be eaten by nearshore egg predators.
This species is also known to undergo male to female sex change. All small individuals are male, and upon reaching a certain size, they change to become female.
Sex change is a common phenomenon among limpets and other groups of marine animals. Though they are not very large no more than a few inches long , common limpets are eaten by people throughout their range. Reprints and Permissions. Gavaghan, H. Lift, drag and separate. Nature Download citation.

When exposed at low-tide, they stay put. Still unresolved is the mystery of how a limpet relaxing on a rock can secrete its chemical glue almost the instant a would-be predator attempts to push it from its perch. Nor is it known how—or how quickly—that liquid lock can be dissolved once the danger has passed, or the limpet is under water. Like all gastropods, or sea snails, its muscle-bound "foot" is in fact a complex animal with a digestive tract , teeth, eyes and organs. In naval warfare , limpet mines are explosive devices attached to a ship with powerful magnets.
But they're probably not as powerful as a limpet's super-glue. Explore further. More from Biology and Medical.
