Anurans or Mice: What is the Best Food Item for Young and Adults of Bothrops jararacussu (Lacerda, 1884) in Captivity?

open access: yesZoo Biology, Volume 44, Issue 4, Page 371-376, July/August 2025.
We use Bothrops jararacussu as a model to introduce three different prey items (mice, exotic anuran – bullfrog and native anurans) in captivity. Our experiments indicated that native anurans could be an interesting food alternative to B. jararacussu and other Bothrops species with an ontogenetic diet in captivity.
