FIGURE 6 in A Phylogenetic Overview of Sponge-inhabiting Barnacles and Their Host Specificity (Crustacea, Cirripedia)
FIGURE 6. Bayesian phylogenetic tree based from CO1 and H3 concatenated sequence data (869 bp). Numbers at nodes represent Bayesian posterior probability values. Numbers on branches represent substitutions per site on that branch. (A) Clade of Acastinae from Philippines and Madagascar in Phyllospongiinae hosts (blue-shaded box); (B) Clade of Bryozobiinae (3 genera) barnacles from Madagascar in encrusting sponge hosts Clathria (Microciona) sp. and Monanchora aff. unguiculata (orange-shaded box); (C) Clade of Eoatria sp. (Bryozobiinae) and 3 undescribed Acastinae barnacles in encrusting sponges (purple-shaded box). All barnacle taxa in this analysis are in the family Archaeobalanidae. All of the taxa identified as members of the Acastinae appear to be undescribed species. Semibalanus balanoides is used as the outgroup in the analysis and is not a sponge-inhabiting species. Numbers on taxon labels are CASIZ specimen catalog numbers.
Fig. 3 in The oldest platylepadid turtle barnacle (Cirripedia, Coronuloidea): a new species of Platylepas from the Lower Pleistocene of Italy
Fig. 3. †Platylepas mediterranea sp. nov., holotype (MSNC 4562). a. Interno-alar view. Note the strongly appressed sheath exhibiting distinct transverse grooves (arrows) and the short, triangular, wedge-like, transverse septa on the sutural edge of the alar portion of the compartment. b. Close-up of the outer surface of the compartment. The outer lamina is only locally preserved; where it is eroded, longitudinally elongated septa and canals are visible. The intersection between longitudinal septa and transverse growth ridges is occasionally marked by small knobs.

Fig. 4 in A new genus and species of barnacle (Cirripedia, Verrucomorpha) associated with vents of the Lau Back-Arc Basin: its gross morphology, inferred first juvenile stage and affinities
Fig. 4. — Schematic plan views and transverse sections of grades of skeletal organization from the most primitive sessile barnacles (A, Brachylepadomorpha) through the asymmetrical sessile barnacles (B-H, Verrucomorpha). Of the eight verrucid genera currently recognized (Young 1998) only the four most representative ones (Altiverruca, Newmaniverruca, Metaverruca and Verruca s.s.) are depicted here. Right sides are to the viewers right and rostral ends are downward in plan views or coming out of the page in transverse sections. The transverse sections are slightly rostral of the rostro-carinal gap or suture. While there are numerous whorls of imbricating plates standing in tiers four plates high in brachylepadomorphs, and on the movable side of neoverrucids, only those of the R-C gap are labeled. Abbreviations: C, R, carina and rostrum; cl1-4, l1-4, rl1-4, carinolateral, lateral and rostrolateral tiers of imbricating plates respectively; cl, rl, the pair of imbricating plates in proverrucids; FS, FT, fixed scutum and tergum; hl, hinge line; L, median latus (completely lost in proverrucids and verrucids); m, myophore; MS, MT, movable scutum and tergum; sam, scutal adductor muscle; S, T, normal terga and scuta in brachylepadomorphs; dashed horizontal lines: membranous basis (transverse sections F-H after Young 1998).
TABLE 1 in A new genus and species of barnacle (Cirripedia, Verrucomorpha) associated with vents of the Lau Back-Arc Basin: its gross morphology, inferred first juvenile stage and affinities
<p>TABLE 1. — Seta/article ratios for four neolepadines compared to four sessile barnacles also from vents: the ratio (the width of the article of an intermediate segment of cirrus VI as the denominator and the length of longest seta of that article as the numerator), while highest in the bacteria-farming neolepadine (Lau sp. A), is lowest in <i>Neoverruca</i>. That for <i>Imbricaverruca</i> as well as for <i>Neobrachylepas</i> are not only similar to each other but fall in the low end of the range for vent barnacles.</p><table><tbody><tr><th></th><th><b>Measurement in mm</b></th><th><b>Ratio</b></th><th><b>Reference</b></th></tr></tbody><tbody><tr><th></th><td><b>article width</b></td><td><b>setal length</b></td><td><b>s/a</b></td><td></td></tr><tr><th>Lau sp.
