Table S 
Analysis of variance results for comparisons among carapace length (CL), year, sex, shell width (SW), 
chela propodus length (ChL), site, depth or stratum, shell condition, bottom temperature (Btemp), 
abdomen width (AW), and maturity (females only) of red deepsea crab {Chaecon quinquedens) cap- 
tured from the Mid-Atlantic Bight during 2011-2013. Other abbreviations: df=degrees of freedom, 
SS=Sum of squares, MS=Mean square, F=F-value, P=P-value.

abundant in the shallow stratum (<450 m), whereas 
new-shell females were most abundant in the deep 
stratum (>700 m). Hard-shell male crab predominated 
in the shallow and deep strata, whereas old-shell crab 
predominated in the middle slope stratum. Hard-shell 
female crab predominated in the shallow strata, where- 
as old-shell females predominated in the middle slope 
and deep strata. 
Bottom temperatures at which crabs were captured 
ranged from 4.6°C to 10.6°C, but mean temperatures dif- 
fered by sex (Table 5). The mean temperatures at which 
crab were captured were 6.27°C (SD 1.18) for males 
(n=1191) and 6.45°C (SD 1.01) for females (n=1624). 
Because these data were not normally distributed, a 
Kruskal-Wallis analysis was conducted and also indi- 
cated significant differences (x^=20.12, P<0.0001). Ovig- 
erous females occurred at slightly colder temperatures 
(6.25°C [SD 0.82]) than those temperatures at which fe- 
males without eggs were found (6.59°C [SD 1.05]; Krus- 
kal-Wallis test (%2=26.69, P<0.0001). Only 11 crabs were 
caught at temperatures above 9.0°C; these crab were 
captured in one sample at a temperature of 11.2°C and
