First Day City: First Day of Issue Ceremony was held in Cleveland, Ohio, at The Great American Stamp Show.
About the Life Magnified Set: These 20 stamps were issued to showcase life undetectable by the human eye alone. All 20 stamps picture photographs taken using special techniques and the aid of a microscope. The set celebrates the beauty and complexity of microscopic organisms and parts of organisms, the study of which have had various impacts on humans.
History the stamp represents: Barnacles are crustaceans that begin life as larvae before attaching themselves to a hard surface. There, they remain stationary for the rest of their lives. Acorn barnacles are one of the most common types of barnacle. In fact, of the 1,445 known barnacle species, 900 are varieties of acorn barnacles.
Acorn barnacles are stalkless barnacles that begin their lives as free-floating larvae. As they grow, they settle and attach themselves to surfaces with a powerful glue-like substance. They then grow hard conical-to-cylindrical shaped shells for protection.
Despite their simple external appearance, acorn barnacles have special adaptations inside their shells that allow them to survive in one spot their whole lives. These include unusual structures called cirri, which the barnacle uses to filter seawater for plankton and other tiny food particles. This is known as suspension feeding. When viewed under a microscope, cirri almost resemble bird feathers. They have similar branching filaments that interlock in a zipper-like way to avoid entanglement in ever-moving ocean currents.
Some scientists have begun studying cirri for ways to build and utilize similar designs in the field of biorobotics. Who knows that useful applications could be discovered thanks to barnacles and their microscopic anatomic structures!
