barnacle etymology

Etymology:

The word "barnacle" comes from the Old French word "bernicle," which is derived from Medieval Latin "bernacularia." The word "bernacula" is thought to be derived from the Latin word "berna," meaning "goose."

Meaning:

A barnacle is a small crustacean that attaches itself to rocks, shells, or other objects in the water. It has a hard, calcareous shell and a feathery crown of cirri, which it uses to filter food from the water.

Origin:

The origin of barnacles is unclear. Some scientists believe that they evolved from insects, while others believe that they evolved from crustaceans. The oldest known barnacles date back to the Carboniferous period, around 300 million years ago.

Additional Information:
