although they are different species - barnacles are arthropods and limpets gastropods they share common environments and also attach themselves to their "home" a in similar manner.
Barnacles are crustaceans, and therefore more closely related to crabs than to mollusks like limpets. The apparent similar morphology of barnacles and limpets is a result of convergent evolution. It does not necessarily require DNA (i.e., similar genotype) in order to produce similar phenotype (physical characteristics).
Both crabs and barnacles have claws and also both shed their external skeleton, the limpets do not.

Barnacles and Crabs are both Crustaceans, while limpets are Molluscs - so I would assume that a barnacle's DNA would be more similar to a crab's.

Sea creatures that attach themselves to rocks include shellfish such as limpets, mussels, oysters, barnacles.
Some examples of clinging shellfish are barnacles, mussels, and limpets. These shellfish attach themselves to rocks, docks, or other hard surfaces using a strong adhesive substance secreted by their bodies.
yes dog whelks are carnivores and feed on barnacles as well as organisms such as limpets.
no
Barnacles don't move once they settle down as a tiny larvae on their chosen surface. Limpets can move around on their broad foot. Some limpets have holes at the top of the hard shell, others do not. The hole is not closed by plates.
