Munida flinti
Benedict, 1902
Munida flinti
has also been reported as
Munida stimpsoni
(see
Baba
et al.
2008
). Its previously reported range is from
Brazil
to the Gulf of
Mexico
in depths of
11 to 641 m
(
Milne-Edwards 1880
;
Henderson 1888
; de Melo- Filho & de
Melo 2001b
). Fifty males, 23 non-ovigerous females, and 47 ovigerous females were measured from a total of
183 specimens
. Male CWs ranged from
3.6 to 13.2 mm
, that of non-ovigerous females ranged from
3.6 to 12.1 mm
, and CW of ovigerous females varied between
3.5 mm
and
12.7 mm
; females were significantly larger than males (t-test, df
=
118, t
=
4.341, p<0.001). Ovigerous females were collected in March, May through August, and October (
Fig. 8
F) and were significantly larger than non-ovigerous females (t-test, df
=
68, t
=
-2.097, p
=
0.040). Fecundity was significantly correlated with size (R2
=
0.598, p<0.001) as was average egg diameter (R2
=
0.282, p<0.001) (
Fig. 4
C). Females had between 55 and 3086 eggs, and the average egg diameter ranged from
0.33 to 0.47 mm
.
