Segmentation is usually indistinct, and the body is more or less evenly divided between the head and thorax, with little, if any, abdomen. The number and size of barnacles that cover ships can impair their efficiency by causing hydrodynamic drag. John Zardus:I was originally interested in barnacles that live on other animals.

Four more plates form a "door" that the barnacle can open or close, depending on the tide.
