Collected
inas Basin NS, Maces Bay NB, Passamaquoddy Bay NB, ponar grab collection of pebbles, hand collection from submerged ropes and scallop drag collection on a scallop bed, 1-60 m depth.
Distinguishing Features
• Shell: 6 grey-white plates, the opercular aperture is a broad diamond shape, the radii are usually narrow with jagged oblique summits and the parieties are rugged, have irregular longitudinal folds and the upper edges are toothed.
• Base: calcified, the crenulate margin is formed by fine radiating furrows on the plates and the basal line is smooth or deeply indented.
• Scutum: no longitudinal striations, somewhat prominent growth lines, a strong articular ridge, absent adductor ridge, a distinct adductor pit and is usually covered by a disintegrating brown membrane.
• Tergum: rather small with short round spar.
• Size: to 30 mm in diameter.
• Profile: conical to cylindrical and inclined to one end.
Habitat
Grows on rocks, stones and shells, 0-90 m depth.
Geographic Range
Boreal distribution in the Northern Hemisphere found from the Arctic to the west coast of France in Europe, the Arctic to Cape Hatteras on the coast of North America and around the Northern Pacific rim from northern Japan to Santa Barbara.
Fun Fact
This barnacle is often one of the first species to settle on newly available hard substrates. It creates habitat complexity and provides additional surface area for colonisation by other species. Both the live and empty tests host a diverse group of sessile and mobile organisms increasing species richness.
Barcode Distribution
BIN matching USA, Canada, the Arctic and Europe.
