Limpets are classified as mollusks: like others in their family, they have strong, sturdy shells and produce slime to help them survive in their aquatic habitats. Limpets’ shells are quite attractive and have a unique cup-like shape that allows them to blend in with rocks along the coastal regions where they live. They also excrete special slime that helps them move over dry rock surfaces and helps with navigation too.
Limpets live among algae deposits on rocky shorelines throughout most temperate regions, including the Atlantic and Pacific shorelines of the United States. They have cup-like shells that are quite strong and protect limpets from harmful sun rays and predators. Their shells vary in appearance and may change color as limpets grow. However, their shells have unique patterns that resemble the surfaces of rocks in their surrounding habitats, which provide camouflage and protection. According to Molluscs, limpets use their shells to fight for scarce food supplies: limpets may drive away barnacles, mussels and other predators from their food supplies by ramming them with their shells. Limpets also produce a slime that enables them to cross rocky surfaces quickly during the day; if unable to move rapidly, limpets risk dehydration when moving in between water sources. The slime that limpets excrete also supports algae growth, which is one of their primary food supplies.
