Description: English: Moulting and growth in Thoracica. Moulting occurs in the cuticular zones separating shell plates. A, new cuticle is formed by infolded epidermis in a narrow growth zone between two adjacent shell plates. B, old cuticle is shed only above the growth zone. The broken-off cuticle leaves distinct growth lines on either side of the growth zone. C, the new cuticle expands by outfolding; the growth zone is not distinct during intermoults. D, a new growth zone forms for the next moult; the shell plate can now expand laterally under the cuticle; older growth lines can thereby be included on top of the plate. Constructed from descriptions by Mahmoud (1959, 1960), Bourget & Crisp (1975) and Blomsterberg et al. (2004). Date: 25 February 2021.

Description: English: Timeline of Thoracican evolution. Generic diversity of the Thoracica from the latest Triassic to the present. Early forms are entirely phosphatic, followed by calcitic pedunculated forms. Balanomorphans (acorn barnacles) appeared in the Cretaceous, but they radiated only after a low-diversity period following the Cretaceous–Palaeogene (K–Pg) extinction. The diversification starting in the Neogene is still ongoing. Living genera shown include only forms with shell plates, in order to compare with the fossil record. Further explanation is given in the main text.

Description: English: Thoracica. A, nauplius larva of Balanus improvisus. Note the presence of frontal horns. B, cypris larva of Amphibalanus amphitrite, showing the pair of extended first antennules and six pairs of thoracopods. C, Anelasma squalicola, a parasite of deep-sea lantern sharks (Etmopterus). The cirri are rudimentary, and the base of the peduncle has a root-like structure embedded inside the tissue of the shark to absorb nutrients. D, Fistulobalanus albicostatus, common on mangrove tree trunks. E, the family Pyrgomatidae are associated with scleratinian corals, and the bases are embedded in the coral skeleton. Cantellius sp. extending the cirri. F, Ibla cumingi, which is located at the most basal position on the molecular phylogenetic tree of thoracican barnacles. G, Megabalanus, Amphibalanus and Lepas inhabiting the capitulum of a penduculated barnacle. H, Capitulum mitella, a stalked barnacle inhabiting rocky shores. In molecular phylogenetic analyses, it is the sister to Anelasma (see C). I, Conchoderma, a stalked barnacle with reduced shell plates, epibiotic on many marine taxa, mostly crabs and whales. J, An early dwarf male settled on the surface of an adult Heteralepas. K, Octolasmis cor lives exclusively on the surface of crab gills. L, Scalpellum scalpellum, a stalked barnacle epibiotic with hydroids. The inserts in LM (upper) and SEM (lower) shows the hermaphrodite receptacles, which can house dwarf males. Inserts show a dwarf male with extended penis (upper) and an SEM micrograph of the receptacle structure. M, Waikalasma is a deep-sea inhabitant, having a row of imbricating plates on the base of shells. N, Chthamalus malayensis is common on intertidal shores. O, Tetraclita, with four shell plates, common on rocky and tropical shores. Date: 25 February 2021. Source: https://academic.oup.com/zoolinnean/article/193/3/789/6149353.

These Goose Barnacles were found attached to this rope which was tied to a drifting wooden fish box of Spanish origin. The specimens were donated to the Macduff Sealife Centre were they thrived for a short time, even producing young.
