Frogs have incredibly long and sticky tongues, capable of lifting 1.4 times their body weight. Their hunting strategy involves waiting for prey and using their ultra-fast tongues to capture agile insects like flies. The tongue's speed and flexibility, aided by powerful muscles, allow frogs to snatch prey in under 0.07 seconds. The tongue's softness helps it wrap around prey, while sticky saliva ensures the prey is trapped. Finally, frogs retract their tongues and use eye pressure to swallow their catch.
