Аннотация:The barnacles of the superorder Acrothoracica having no external mineral shells, bore into calcareous
substrates in the marine environment, such as molluscan and thoracican shells, corals, bryozoans and calcareous
rocks (Tomlinson 1969, 1987). During the voyage of H. M. S. Beagle, Darwin discovered his first barnacle, an
acrothoracican barnacle within a gastropod shell from Chile (Tomlinson 1987; Fig. 1). The distinct morphology
of this barnacle stimulated Darwin’s interest and Darwin named this specimen as ‘Mr Arthrobalanus’ and later
described as Cryptophialus minutus Darwin, 1854 (Fig. 1B, C, Fig. 2). The examination of ‘Mr Arthrobalanus’
attracted Darwin to examine the diversity of the whole group of the Cirripedia, leading to almost a decade of
study into cirripede taxonomy and evolution.
The morphology and habitat of acrothoracican barnacles are highly diversed. Lithoglytid species which are
filter feeders boring in molluscan shells (Fig. 3A-C) and corals (e.g. Berndtia species, Fig. 3D-E, H). Trypetesid
species are detritivores, boring in the columella of the gastropod shells in hermit crabs (Fig. 3F, G) and a previous
study has pointed out Trypetesa lampas feed on the eggs of hermit crabs (Williams et al. 2011).
