TL;DR: Twelve species of barnacles were identified from the fouling community on the parts of the ‘Maui’ oil platform that were submerged during its tow from Japan in 1975 and after its arrival in New Zealand.
Abstract: Twelve species of barnacles were identified from the fouling community on the parts of the ‘Maui’ oil platform that were submerged during its tow from Japan in 1975 and after its arrival in New Zealand. The stalked barnacles Lepas anatifera L. var. (a) Darwin, L. anserifera L., Conchoderma auritum (L.), and C. virgatum (Spengler) probably settled during the tow across the tropical Pacific, and have been recorded in New Zealand waters before from ships (the Lepas spp.) and vertebrates (the Conchoderma spp.). The acorn barnacles were small, and probably settled in Japanese waters; Balanus variegatus Darwin and B. amphitrite Darwin already occur in northern New Zealand waters. The other six species—B. improvisus Darwin, B. albicostatus Pilsbry, B. reticulatus Utinomi, Megabalanus volcano (Pilsbry), M. rosa (Pilsbry), and Tetraclita squamosa japonica Pilsbry—have not been recorded from New Zealand before.
TL;DR: The present annotated checklist contains 43 species of thoracican barnacles known to date from the area, 33 and 26 from the Persian Gulf and the Gulf of Oman, respectively.
Abstract: The present annotated checklist contains 43 species of thoracican barnacles known to date from the area, 33 and 26 from the Persian Gulf and the Gulf of Oman, respectively. Nine species are new records for the area including Amphibalunus subalbidus (Henry, 1973), Armatobalanus allium (Darwin, 1854), Chelonibia patula (Ranzani, 1818), Conchoderma hunteri (Owen, 1830), Lepas anserifera Linnaeus, 1767, Lithotrya valentiana Reinhardt, 1850, Megabalanus coccopoma (Darwin, 1854), Megabalanus occator (Darwin, 1854) and Platylepas hexastylos (Fabricius, 1798), of which A. subalbidus and M. coccopoma are reported as alien species from the region.
TL;DR: An example of the rapid growth in pedunculate barnacles has been seen in a mixed population of Lepas anatifera and Conchoderma virgata taken from the newly painted surface of a buoy recovered off the east coast of Australia on December 2, 1960.
Abstract: AN example of the rapid growth in pedunculate barnacles has been seen in a mixed population of Lepas anatifera and Conchoderma virgata taken from the newly painted surface of a buoy recovered off the east coast of Australia (31° 14′ S., 153° 12′ E.) on December 2, 1960. The buoy was laid (30° 36′ S., 153° 28′ E.) 17 days previously and on recovery was coated with large barnacles, some releasing larvae. The maximum dimension of the capi-tulum was measured (Fig. 1); in preserved material this is half the total length.
TL;DR: Two species of Conchoderma were found on a sea snake, Laticauda semifasciata, collected on the west coast of the Kii Peninsula, and the distribution of C. virgatum on the snake was non-random both longitudinally and dorso-ventrally, with more barnacles in the posterior region and on the ventral side of the snake, respectively.
Abstract: Two species of Conchoderma were found on a sea snake, Laticauda semifasciata (Reinwardt), collected on the west coast of the Kii Peninsula. A total of 223 individuals of C. virgatum and 6 of C. hunteri in 19 clumps were attached to the snake's body. The barnacles ranged in size from 1.4 mm (cypris larvae) to 18.2 mm in capitulum length in C. virgatum, and from 10.7 to 14.4 mm in C. hunteri. The size of the smallest gravid individuals in both species was between 10 and 11 mm. The distribution of C. virgatum on the snake was non-random both longitudinally and dorso-ventrally, with more barnacles in the posterior region and on the ventral side of the snake, respectively. The proportion of gravid individuals increased towards the tail.
TL;DR: Some damage observed on the bell surface of the jellyfish suggest that the epibiont affected the growth of its host negatively, although C. virgatum is not considered an obligate parasite.
Abstract: The association between the scyphomedusae Stomolophus meleagris (Agassiz 1862) and a cirripede indentified as Conchoderma cf virgatum (Spengler, 1790) in the Gulf of California was recorded for the first time on April 2010, during the fishing season of edible jellyfish in Guaymas, Mexico. Despite its wide distribution,records on this barnacle are scarce on the coast of Mexico, so this note is one of the few reports of C. virgatum in the Gulf of California and the first record of symbiosis with jellyfish S. meleagris worldwide. Some damage observed on the bell surface of the jellyfish suggest that the epibiont affected the growth of its host negatively, although C. virgatum is not considered an obligate parasite.
