Frogs and amphibians can nab a fly with remarkable speed — but the real secret of their bug-catching prowess is in the saliva.
Sticky frog saliva is a non-Newtonian fluid. That means it can behave as both a liquid and a solid.
This unusual combination of tongue and saliva allows a frog to catch insects,...(image)
