Munidopsis erinacea
was the sixth species in terms of abundance (n = 72). The highest abundance was observed in the sector ESE during the spring season in a depth range of 700-799 m. The ANOVA analysis was made only for males (n = 37), but did not show significant differences by depth [F (3;32) = 1.1295; p = 0.3518] or season [F (2;33) = 3.0006; p = 0.0635]. The mean size of males was x = 14.0
+/-
3.954 (6.0-21.4) at 406-780 m depth range. The mean size of females was x = 10.4
+/-
3.346 (6.4-18.0) at 530-820 m depth. The mean size of ovigerous females was x = 12.7
+/-
2.431 (8.3-17.1) at 530-820 m depth.
The ovigerous females were observed in all seasons; however, they were more numerous during spring in the ESE sector. Sex ratio was similar in all seasons (1 M: 1 F). Two individuals were infested by rhizocephalans (CL male = 15.9 mm, female = 17.0), and one female (CL = 13.1 mm) was infested by bopyrid.
