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

This species is easily confused with M. angulata ( Baba et al. 2008 ) and such may be the case with some of these specimens. We used specimens collected in the Gulf of Mexico and Caribbean in depths of 12 to 200 m . Specimens were collected in all months; ovigerous specimens were not collected in December ( Fig. 9 E). One hundred eighty-six males (CW from 1.6 to 8.5 mm ), 64 non-ovigerous females (CW from 2.0 to 8.3 mm ), and 86 females were measured (CW from 2.1 to 7.4 mm ); males and females were not significantly different in CW (t-test, df = 336, t = 0.0455, p = 0.964) nor did ovigerous females and nonovigerous females differ in size (t-test, df = 148, t = -0.893, p = 0.373). Females had between four and 772 eggs with average egg diameters range of 0.19 to 0.55 mm . Fecundity was significantly correlated with CW (R2 = 0.513, p <0.001) ( Fig. 4 F), and the average egg diameter was correlated with the CW (R2 = 0.183, p value<0.001).
