Munidopsis robusta (A. Milne-Edwards, 1880)

Munidopsis robusta has also been reported as Galathodes robusta and has a distributional range from the Gulf of Mexico to French Guiana in depths of 291 to 824 m (Milne-Edwards 1880; Pequegnat & Pequegnat 1970; Takeda 1983). Specimens in this analysis were from the Caribbean and the Gulf of Mexico in depths of 79 to 960 m. Specimens were collected in every month except January; ovigerous specimens were collected in every month except January (Fig. 13 F). Eighty-seven males (CW from 3.9 to 14.8 mm), 43 non-ovigerous females (CW from 5.6 to 15.7 mm), and 55 ovigerous females were measured (CW from 11.2 to 17.3 mm). Females were not significantly larger than males (t-test, df = 183, t = 1.804, p = 0.073); ovigerous females were significantly larger than non-ovigerous females (t-test, df = 96, t = 7.868, p<0.001). Females had between nine and 371 eggs with average egg diameter for each female ranging from 0.96 to 1.7 mm. Fecundity was correlated with CW for M. robusta (R2 = 0.209, p = 0.014) (Fig. 10 F), but average egg size was not correlated with CW (R2 = 0.0577, p = 0.218).
