P.13 5th paragraph: "Most extreme sexual size dimorphism—Females weighing 125 times that of males. Sexual size dimorphism is a morphological syndrome in which conspecific male and female sizes differ significantly. Among terrestrial animals, the most extreme female-biased gigantism is found in orb-weaving spiders (Foellmer & Moya-Laraño, 2007). Golden orb-weaving spiders (Araneidae) are the most extremely sexually size dimorphic. Female on average can be up to 125 heavier than mating males (primary source) (Fig. 3G)." |
