Friends or Foes? Emerging Impacts of Biological Toxins [PDF]

, 2019
Toxins are substances produced from biological sources (e.g., animal, plants, microorganisms) that have deleterious effects on a living organism. Despite the obvious health concerns of being exposed to toxins, they are having substantial positive impacts

Evolution: Fangtastic Venoms Underpin Parasitic Mimicry [PDF]

, 2017
Venomous teeth are rare in fishes, which typically utilise spines for defence. A new study reveals the evolutionary origins of fangs and venom in the Nemophini blennies and shows that, in contrast to snakes and lizards, the fangs pre-date the ...
