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
As an adult, D. fascicularis lives attached to a float made either of natural
flotsam or of a cement it
secretes itself, which has a texture like that of
expanded polystyrene foam .
[4] It is the only barnacle to produce its own gas-filled float.
[2] The
cyprid
larvae are
planktonic , and must attach to a float for
metamorphosis into the adult form, but the adults are eventually capable of using their own float, sometimes forming aggregations of many individuals attached to a single float. Among the floats used by adult buoy barnacles are pellets of
tar ,
[5]
seaweeds ,
[2]
[6]
plastic
debris ,
[6]
driftwood ,
[6]
feathers ,

cuttlefish bone ,
[2] the "by-the-wind-sailor"
Velella velella ,
seagrass
leaves ,
[3]
Styrofoam ,
[5]
seeds ,
[5] and even
apples ;
[2] they have even been known to colonise the backs of
turtles
[7] and the
sea snake
Pelamis platurus .
[8] It is a
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.

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
cosmopolitan distribution , with a preference for
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 .
