- Semibalanus is a genus of acorn barnacles. Semibalanus balanoides is the most widespread intertidal barnacle in the British Isles1. It is a filter feeder, using its thoracic appendages, or cirri, to capture zooplankton and detritus from the water2. Semibalanus cariosus is a species of acorn barnacle occurring in the northern Pacific Ocean34. It may grow up to 60 mm in diameter and has 6 unequal-size shell plates with cascading longitudinal ribs resembling a thatched roof4.Learn more:✕This summary was generated using AI based on multiple online sources.

Semibalanus balanoides is the most widespread intertidal barnacle in the British Isles. It may grow up to 15 mm in diameter and has 6 calcified grey-white shell plates. It may be distinguished from other barnacles by the presence of a diamond shaped opercular aperture and a membranous shell base.
www.marlin.ac.uk/species/detail/1376Semibalanus balanoides is a filter feeder, using its thoracic appendages, or cirri, to capture zooplankton and detritus from the water. If there is a current, then the barnacle holds its cirri stiffly into the flow, but when there is no current, the barnacle beats its cirri rhythmically.

Adult S. balanoides grow up to 15 millimetres (0.6 in) in diameter, and are sessile, living attached to rocks and other solid substrates. They have six greyish wall plates surrounding a diamond-shaped operculum. The base of the shell is membranous in Semibalanus, unlike other barnacles which have calcified bases. When the tide rises to cover the barnacles, the operculum opens, and feathery cirri (modified thoracic appendages) are extended into the water to filter food from the se…
