Barnacles do not sleep in the same way that many animals do, but they do enter a state of reduced activity and metabolic rate during certain periods. They are primarily active during tidal cycles, feeding and filtering water, and may become less responsive when submerged or during periods of low tide. This state is not a true sleep but rather a form of dormancy that helps them conserve energy and survive environmental fluctuations.

Barnacles are crustaceans( a type of arthropods)
commensalism

Barnacles are shellfish that cling to rocks or ships hulls.
Barnacles live only in salt water.
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit by getting a free ride through the water and access to nutrients. The whales are not significantly affected by the presence of the barnacles.
