Scientists have discovered that the chitin fibres in the fangs of a large Central American wandering spider are arranged and surrounded with proteins in a way that makes the material particularly rigid and thus capable of penetrating its prey’s cuticular armour. Thanks to the composition and structure of their materials, the fangs become optimised and reusable hypodermic needles for injecting prey with paralysing venom.
