Figure 5 in The taxonomic status of some Atlanto-Mediterranean species in the subgenus Holothuria (Echinodermata: Holothuroidea: Holothuriidae) based on molecular evidence
Figure 5. Main variables selected by the stepwise discriminant function analysis to distinguish clade 1 – Holothuria mammata (upper box, dark grey colour), clade 2 – Holothuria tubulosa (middle box, clear grey colour), and clade 3 – Holothuria dakarensis (bottom box, white colour). A–F, variables that characterize function 1. G–H, variables that characterize function 2. The centre lines of the boxes mark the median value, the hinges the lower and upper quartiles, respectively, and the whiskers the range of data between values smaller/greater than the lower/upper quartile minus/plus 1.5 times the interquartile range; asterisks represent outliers (data values outside of this range); and squares represent unusually small or large values outside of the outer fences.

After these, the clade (1–3) and the name of the species are provided.
