Overview

Interesting Facts

Common Names

Description

Physical Description

Habitat

Prefers open, surf-swept coastlines. It has also been reported to occur on other barnacles on the skin of Humpback Whales . Depth Range : M. polymerus occurs in the high to middle intertidal zones. [1]

Biology

Diet

Feeds by growing outward so that it can extend its cirri in a fan oriented perpendicular to the backwash of the waves. Small particles of detritus and tiny crustaceans get caught in the cirri, which are subsequently eaten.[1]

Reproduction

In the Puget Sound , Goose Neck barnacles breed from April to October, peaking in July. Individuals are hermaphroditic , but will always cross-fertilize. Each sexually mature individual may produce up to four broods per year, with up to 20,000 developed young per brood. The young aggregate at the base of the adults , where their survival rate increases. Within one month they are able to attain independence . [1]

Behavior

Predators of M. polymerus include the ochre sea star (Pisaster ochraceus) and the Glaucous-winged Gull (Larus glaucescens). M. polymerus directly competes with the California Mussel (Mytilus californianus) and can often out-compete them. M. polymerus often grows in tight bunches (rosettes) which make them more resistant to predation .[1]

Taxonomy

Synonyms

Similar Species

There is a pelagic goose barnacle, Lepas anatifera, frequently found in the Pacific Northwest that looks somewhat similar to M. polymerus, however is has fewer plates and only occurs in the open sea and on driftwood washed ashore. There is a closely related European species, Pollicipes pollicipes, which is cooked and served as a delicacy. However, it is now in short supply and M. polymerus has been exported from British Columbia to Portugal and Spain. (Ref. 109953)
