Figure 2. Anatomical and morphological characteristics of the male phase (a���c) and female phase (d��� f) individuals of Merguia rhizophorae (Rathbun 1900). (a) Close-up of the endopod of the first pleopod (arrow points to the cincinnuli); (b) Endopod of the second pleopod (upper and lower arrows point to the appendix interna and the appendix masculina, respectively); (c) Gonopore on the coxae of the fifth pereiopod (arrow points to the gonopore); (d) Close-up of the endopod of the first pleopod (arrow points to the area where cincinnuli would be located in a male phase); (e) Endopod of the second pleopod, lacking an appendix masculina (arrow points to the appendix interna); (f) Coxae of the fifth pereiopod, lacking a gonopore (arrow points to the area where gonopore would be located in a male phase).
