Species Information


Distribution

Size large, capitulum up to 43 mm (1¾ inches) in length, peduncle up to 8 inches in length. Capitulum enclosed in five finely striated plates. A tooth is usually present on the lower angle of the right scutum, but is often absent from the left. A series of square spots often present on the scutum. Space between carina and other valves narrow. Never more than two branchiae on each side. Scales irregularly scattered over peduncle in mature specimens; minute spines are present on young individuals.

Colour

Dirty white or bluish-grey on plates, bright scarlet-orange on edges of orifice. Dull orange-brown on interspaces; purplish-brown on peduncle.

Distribution

World-wide, often attached to driftwood.

Notes

This is perhaps the most common pedunculate barnacle, being found on driftwood all along the coast. It resembles Lepas hilli very closely but can be distinguished from it by the presence of fine striations on the valves and one pair of filamentary appendages (branchiae) on each side of the body. The name "anatifera," meaning goose-bearer, refers to the legendary origin of the barnacle goose.
