Barnacles and Relatives: Thecostraca - Barnacles, Their Relatives, And People
darwin bottoms
Native Americans once ate barnacles. Today, the rock barnacle is popular as seafood in parts of South America. Many other barnacles are considered pests. When attached to the bottoms of ships, barnacles can slow their speed by more than one-third. This increases the amount of fuel needed to get from place to place. Much time, money, and effort has been spent on the development of paints that will prevent barnacles from settling on ship bottoms.
