Overall Geographic and Bathymetric Distribution.
This species has been recorded off Cape Hatteras (
North Carolina
,
U.S.A.
) to off Recife (NE
Brazil
), the entire Gulf of Mexico (NW; NE; SW;
SE
) and Caribbean Sea; at a
707–1760 m
depth range (
Holthuis, 1971
;
Felder
et al
. 2009
).
Distribution in the Southwestern and Southeastern Gulf of
Mexico
.
We collected this species in
Tamaulipas
: Laguna Madre (WNW); in front of
Veracruz
: Nautla and Coatzacoalcos rivers (WSW);
Tabasco
: Carmen-Machona Lagoons, Grijalva-Usumacinta rivers (SSW);
Campeche
: San Pedro-San Pablo rivers, Términos Lagoon (SSW);
Yucatán
: N of Alacranes reef (ESE); at a depth range of
443.8 to 1144 m
. It was found inhabiting clay and shell sediment (
Fig. 4
).

Remarks.
A total of 242 individuals of
G. aculeata
was collected in all cruises. Although this species occur in the entire Gulf of
Mexico
, we obtained the highest abundances in the sectors SSW and ESE, stations located in front of Coatzacoalcos River (
867 m
depth) and W of Alacranes reef,
Yucatán
(
828.9 m
depth). Sex ratio was 4.6 females to
1 male
; ovigerous females accounting 57.3 % of the total females. Length carapace distribution showed that males were smaller than females. Ovigerous female size range was 15.1–32.0 mm (mean 25.32 ± SD) whereas females varied between
10.8–30.7 mm
CL (mean 20.53 ± 3.99 SD), and males size range was
12.8–23.2 mm
CL (mean 18.7 ± 2.62 SD) (
Fig.5a, b, c
).
The widest depth distribution range was observed in the ovigerous females (
443.8–1047 m
) compared to the non-ovigerous females and males depth distribution range (681.6–1044.0 and 620.0–
1144 m
, respectively). The ovigerous females occurred in spring, summer and autumn at depths between
800–899 m
; but the maximum number was registered in summer (COBERPES 2009) off the Coatzacoalcos River. Although we observed a tendency of minor sizes to be present at deepest intervals, the ANOVA did not show a significant difference (males: F= 1.706, p= 0.1686; females: F= 1.9583, p= 0.0937; ovigerous females: F= 6721, p= 0.6454).
