Munida irrasa A. Milne-Edwards, 1880

Munida irrasa has also been reported as M. caribea (see Baba et al. 2008). This species has been reported from Brazil to the Gulf of Mexico to the southern coasts of New England in depths of 38 to 483 m ( Milne-Edwards 1880; Smith 1883; Chace 1942; de Melo-Filho 2006). In the collections, 228 specimens were collected from the Caribbean and Gulf of Mexico. Six males, six females, and one ovigerous female were measured for this analysis. Male CW ranged from 4.0 to 8.3 mm, non-ovigerous female CW ranged from 4 to 6.9 mm; the ovigerous female had a carapace width of 6.8 mm; males and females were not significantly different in size (t-test, df = 11, t = - 0.583, p = 0.572). The ovigerous female had 252 eggs. In collections, specimens were collected in all months except October, November, and December; these were the same three months in which no ovigerous specimens were collected ( Fig. 9 A).
