Why do frogs have such sticky tongues?
Quick Answer
Frog tongues are coated with mucus and can snap out extremely fast to catch prey. The tongue tip and saliva become even stickier during the strike.
The Full Story
A frog’s tongue is specialized for rapid prey capture. When a frog strikes, the tongue flips outward with high speed and then retracts, often bringing insects back into the mouth in a fraction of a second. Researchers have found that the saliva becomes more fluid during the strike and then more viscous on impact, helping it adhere to prey. This mechanism is particularly effective for small, fast insects. The tongue’s speed and stickiness make frogs efficient hunters despite their small size.
