Milne-Edwards, 1880 ) Munidopsis erinacea has been reported as Munidopsis erinaceus and Galathodes erinaceus (see Baba et al. 2008 ) from Brazil to the Gulf of Mexico in depths of 238 to 1574 m ( Milne-Edwards 1880 ; Chace 1942 ; Tavares & Campinho 1998 ; Campos et al. 2005 ). Specimens in this analysis were from within the published depth ranges of the species in depths of 344 to 1487 m . Specimens were collected in every month; ovigerous specimens were collected in every month except August and January ( Fig. 12 G). One hundred fifteen males (CW from 3.3 mm 19.5 mm ), 50 females (CW from 3.2 to 11.0 mm) and 44 ovigerous females (CW from 5.1 to 12.7 mm ) were measured. Males were significantly larger than females (t-test, df = 207, t = -2.102, p = 0.037); ovigerous females were significantly larger than non-ovigerous females (t-test, df = 90, t = -3.483, p<0.001). Females carried between one and 82 eggs with an average egg diameter of 1.02 to 1.33 mm . Fecundity was correlated with CW (R2 = 0.432, p = 0.004) ( Fig. 10 C), but average egg diameter was not correlated with CW (R2 = 0.113, p = 0.203).
