Figure 4 in What can goby otolith morphology tell us?

Figure 4. – Box plots of eight otolith variables that were useful in the separation of the five oxudercid lineages. A: Ratio of sulcus area and otolith area. B: Ratio of sulcus perimeter and otolith perimeter. C: Ratio of sulcus perimeter and distance from sulcus end to the ventral margin. D: Ratio of sulcus length and otolith length. E: Ratio of sulcus length and distance from sulcus end to the ventral margin. F: Ratio of sulcus length to otolith perimeter. G: Ratio of distance from sulcus tip to the ventral margin and distance from sulcus end to the ventral margin. H: Ratio of distance from sulcus end to the ventral margin and otolith perimeter. Abbreviations: Ac, Acanthogobius lineage; Mu, Mugilogobius lineage; Pe, Periophthalmus lineage; Po, Pomatoschistus lineage; St, Stenogobius lineage; †Po, †Pomatoschistus sp. from Brzobohatý (1994).
