Eating In The Blink Of An Eye
"A new Georgia Institute of Technology study says the stickiness is caused by a unique reversible saliva in combination with a super soft tongue. A frog's saliva is thick and sticky during prey capture, then turns thin and watery as prey is removed inside the mouth."

Frogs use a viscoelastic tongue and non-Newtonian saliva to catch prey
"Frogs can capture insects, mice and even birds using only their tongue, with a speed and versatility unmatched in the world of synthetic materials. How can the frog tongue be so sticky? In this combined experimental and theoretical study, we perform a series of high-speed films, material tests on the tongue, and rheological tests of the frog saliva."

Slip of the tongue: Chameleon's sticky secret revealed
"Several mechanisms have been proposed: suction, stickiness, or a velcro-like bond between a rough surface on the chameleon's tongue and that of its meal, which can weigh a third as much as the predator itself. On Monday, scientists in Belgium and France said the answer was sticky mucus on the tongue tip."
