Fig 1.
Basal shells of Xenobalanus globicipitis.
Shells attached on the dorsal side of the flukes, close to the notch, of the striped dolphin, Stenella coeruleoalba. Scale bar: 2 cm.
Fig 2.
Area colonized by Xenobalanus globicipitis.
Diagram of dolphin flukes (a), flipper (b), and dorsal fin (c), highlighting the area where individuals of X. globicipitis were found on the striped dolphin, Stenella coeruleoalba.
Fig 3.
Microhabitats defined for the study of the habitat selection for Xenobalanus globicipitis on the flukes of the striped dolphin, Stenella coeruleoalba (see the text for details).
Fig 4.
Orientation criterion for the basal plate.
Diagram of a basal plate of Xenobalanus globicipitis and criterion used to orient it with respect to the edge of the fluke of the striped dolphin, Stenella coeruleoalba (see the text for details).
Fig 5.
Pattern of occurrence of Xenobalanus globicipitis on swimming appendages using the criterion of maximum nesting.
Each column shows an individual striped dolphin, Stenella coeruleoalba, and the presence of the barnacle on each appendage is represented by a black rectangle. The bars below indicate the number of appendages colonized.
Fig 6.
Percent occurrence of Xenobalanus globicipitis on flukes, flippers, and dorsal fin of 96 striped dolphins (Stenella coeruleoalba).
Triangles indicate actual figures, and circles indicate expected figures in a total of 96 striped dolphins, Stenella coeruleoalba, assuming that the probability of colonization depends on space provided on each fin (see text for details). Bars represent the 95% confidence interval.

Parameters of predictors in a mixed model that accounts for the median shell diameter of Xenobalanus globicipitis on the flukes, flippers and dorsal fin of the striped dolphin, Stenella coeruleoalba, from the western Mediterranean Sea.
Fig 7.
Average abundance of Xenobalanus globicipitis on caudal fin.
Dorsal side (squares) and ventral side (diamonds) of three sections of the caudal fin of striped dolphins (see also Fig 3). Bars represent the 95% confidence interval.
Table 2.
Average values of median shell diameter (S.D.) of Xenobalanus globicipitis on the dorsal and ventral sides of 3 sections of the flukes (see Fig 3) of the striped dolphin, Stenella coeruleoalba, from the western Mediterranean Sea.
