Order
Common name: Goose Barnacles
Scientific name: Pedunculata
Pedunculata, commonly known as goose barnacles or stalked barnacles, are an order of crustaceans found in marine environments. They are characterized by their long, fleshy stalks, called peduncles, which attach to hard surfaces such as rocks, ship hulls, and flotsam. Unlike their acorn barnacle relatives, Pedunculata are sessile filter feeders that use feather-like cirri to capture plankton from the water. In the aquarium, they can be fascinating additions but require stable water conditions and adequate flow to thrive. They are not commonly kept due to their specific feeding requirements and sensitivity to changes in water quality.
