Figure 5 in The atyid shrimp (Crustacea: Decapoda: Atyidae) rostrum: phylogeny versus adaptation, taxonomy versus trophic ecology

Figure 5. Examples of rostra in some populations of Troglocaris s. str. phylogroups according to presumable absence (specimens on left) and presence (specimens on right) of Proteus sp. appropriately chosen to represent adequately the whole variability in shape and length of the rostrum. Sample numbers (as in Table 1) and sex (m, male; f, female) are added. Although probable, the presence of Proteus in localities denoted with hash mark ("#") could not be verified.
