Finally we tested how venom yield changed 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 we found previously in snakes (onlinelibrary.wiley.com/doi/abs/10.1...).
Snake venom potency and yield are associated with prey‐evolution, predator metabolism and habitat structure
Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those cap....

We also tested for evolutionary trade-offs between venom potency and silk use in prey capture but find no relationship. This was surprising as we previously found such a trade off between scorpion pincer size and potency but this does not seem to be the case for spiders. www.mdpi.com/2072-6651/14...

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