Of the nearly 6,800 extant frog species, most have weak jaws that play only a minor role in
prey capture. South American horned frogs (Ceratophrys) are a notable exception …

Frogs are well known to capture fast-moving prey by flicking their sticky tongues out of the
mouth. This tongue projection behaviour happens extremely fast which makes frog tongues …

It is well known that capture silk, the main sticky component of the orb web of a spider, plays
an important role in the spider's ability to capture prey via adhesion. However, the detailed …
