Males can have a longer head than females (longer anterior region). See this article: http://condor.depaul...Akinpelu_10.pdf

(Females are not more heavy set/ deeper-bodied than males except during breeding season.)
Our lab uses genetics as the only absolute method of accurately sexing G. aculeatus, unfortunately! Outside breeding season, they are tricky to sex due to high variability in phenotype/ body shapes among populations.
