Reproductive biology of galatheoid and chirostyloid (Crustacea: Decapoda) squat lobsters from the Gulf of Mexico Author Kilgour, Morgan J.

Milne-Edwards, 1880 Galathea rostrata has been reported throughout the Caribbean and Gulf of Mexico to North Carolina in depths of 22 to 92 m ( Milne-Edwards 1880 ; Milne-Edwards & Bouvier 1897 ; Haig 1956 ; Baba et al. 2008 ). The specimens used in this analysis were from the Gulf of Mexico and off the coast of Florida in depths of 30 to 100 m ( Fig. 5 ). Specimens were collected in every month except December ( Fig. 6 ). A total of 274 specimens was in collections with 145 males , 65 ovigerous females, and 64 non-ovigerous females; only 104 males , 42 ovigerous, and 41 non-ovigerous females were measured. Male carapace width ranged from 1.3 to 5.8 mm . Non-ovigerous female CW ranged from 1.3 to 4.8 mm . Ovigerous female CW ranged from 1.9 to 5.4 mm . The average egg diameter for each female ranged from 0.22 to 0.48 mm , and the number of eggs ranged from one to 204. Males and females did not vary significantly in size (t-test, df = 185, t = 0.825, p = 0.411), but ovigerous females were larger than non-ovigerous females (t-test, df = 81, t = -2.382, p = 0.020). Fecundity was not significantly correlated with the size of the ovigerous females (R2 = 0.264, p = 0.082) nor was the average egg diameter correlated with size (R2 = 0.130, p = 0.092).
