Group of buoy barnacles attached to a float they constructed themselves

Dosima fascicularis, the buoy barnacle, is "the most specialised

pleustonic goose barnacle" species.[3] It hangs downwards from the water surface, held up by a float of its own construction, and is carried along by ocean currents
.

Flotation

See also: Ocean surface ecosystem

As an adult, D. fascicularis lives attached to a float made either of natural

fugitive species, which can be out-competed by other barnacle species, and relies on being able to colonise surfaces and reproduce quickly; after settling on a float, D. fascicularis can reproduce within 45 days.[9] D. fascicularis appears to be increasing in abundance as a result of anthropogenic marine debris accumulating in the sea;[5] this source of floats was of "minor importance" in 1974.[3]

Related species

Although formerly placed in the genus Lepas, the buoy barnacle is now generally placed in the genus, Dosima. Dosima is distinguished from Lepas by the form of the carina, and by the exceptional thinness and brittleness of its exoskeleton.[10]

Distribution

D. fascicularis has a

temperate seas,[11] having been found at latitudes from 71° North off Siberia to 57° South near Cape Horn.[2] Groups have been observed journeying from Japan to the Hawaiian Islands in the Pacific Ocean,[2] and sometimes wash up on westerly and southerly beaches in the British Isles, as well as westerly beaches further south in Europe.[4][12] It is not normally found in the Mediterranean Sea, but may have begun to colonise there from the Atlantic Ocean.[13]
