Barnacles

A walk along the seashore at low tide reveals colonies of barnacles stuck to every hard surface. These crustaceans are related to lobsters, crabs, and shrimp.

A shrimp-like barnacle larva ready to settle down sticks its head to an object with its own superglue, then builds up calcium protective plates. The barnacle remains closed up inside, except when it filters food from the water with its fringed feet.
