Finally, we tested how venom yield scaled with body size, finding allometric scaling close to 0.75, suggesting that metabolic costs are one of the main drivers of venom production, similar to what was found previously in snakes (onlinelibrary.wiley.com/doi/abs/10.1...).

We also tested for evolutionary trade-offs between venom potency, body size and silk use in prey capture but find no relationship between either size or silk use with venom potency which was unexpected and is both supported and contested by other studies in the literature.

By comparing over 70 species we show that spider venoms have evolved to be phylogenetically prey-specific by testing how venom potency changed when tested on animals closely related to a spiders diet compared to when tested on species more distantly related to their diet.
