H.swammerdami males will be a lot more elongated compared to females
Other than that and pectines, there is no sexual dimorphism in H.swammerdami


NB: The male is brown because he moulted recently, colour is no way to tell sex

Males are a bit longer though I think there the same bulk wise and I’m pretty sure the amount of aggression/ defensive behavior varies from individuals.
