We cultured larvae of 9
cirripede species to the cypris stage: Megabalanus rosa Pilsbry, 1916 (n = 6), Austrominius (=Elminius) modestus (Darwin, 1854) (n = 6), Semibalanus balanoides (Linnaeus, 1767) (n = 6), Balanus crenatus Bruguiere, 1789 (n = 11), Perforatus (Balanus) perforatus (Bruguiere, 1789) (n = 5), Hesperibalanus fallax (Broch, 1927) (n = 9), Balanus balanus (Linnaeus, 1758) (n = 1), Balanus spongicola Brown, 1844 (n = 4), and Verruca stroemia (O.F.
Growth, fecundity, and reproductive biology in the pedunculate
cirripede Pollicipes polymerus at San Juan Island, Washington.
The morphology of the third segment in
cirripede cyprids varies markedly in shape and structural features, but the explanation for this remains unclear.
TEM studies on the lattice organs of
cirripede cypris larvae (Crustacea, Thecostraca, Cirripedia).
The morphology of the
cirripede central nervous system is unique amongst arthropods in that it has undergone extensive modification associated with the sessile mode of life in the adult barnacle.
Distribution and variation in form of the
cirripede Octolasmis cor (Aurivillius, 1893) in relation to the respiratory current of its host Scylla serrata.
We have examined the cyprid larvae of nine species of
cirripedes and found that their thoracopods always have fused setal arrays of the three types: within and between podites and between appendages (though the number of linked setae varies between species).
Tar pellets and plastics as attachment surfaces for lepadid
cirripedes in the North Atlantic Ocean.
The reproductive periods and condition of the penis in several species of common
cirripedes. Oceanogr.
The Balanidae (or sessile
cirripedes; the Verucidae, etc.).
On gross examination, the most remarkable findings were moderate to severe multiorgan parasitic infection, mainly
cirripedes (Xenobalanus sp.) in the caudal fin; larval cestodes (Phyllobothrium sp.
For instance, the several species of the Chthamalinae (a sub family of sessile
cirripedes) coat the rocks all over the world in infinite numbers: they are all strictly littoral, with the exception of a single Mediterranean species, which inhabits deep water and has been found fossil in Sicily, whereas not one other species has hitherto been found in any tertiary formation: yet it is now known that the genus Chthamalus existed during the chalk period.
The seasonal changes in body weight, biochemical composition and oxygen uptake of two common boreo-artic
cirripedes, Balanus balanoides and B.
And so in the years between, his seasick voyage to the Galapagos on the Beagle and the publication of his masterwork on the origin of species--even as he wrote four long monographs about what he saw while supporting his wrists on wooden blocks to dissect
cirripedes the size of pinheads--he was writing a Prime Mover out of the big picture: "the strongest wings, the largest mouth, the longest legs ..."
On the most battered shores there are organisms able to withstand the beating of the waves, especially mussels,
cirripedes, and limpets.
