Their breathing and heartbeat are temporarily stopped during this state.Prior to hibernation, they produce a liquid called glycerol in their blood which lowers their freezing point.
Adults enter this state on land and can be found under decaying logs or leaf litter.During cold winter months, it protects itself by hibernating or becoming dormant as if it is in a deep sleep.The Cope's gray tree frog is cold-blooded and does not produce its own body heat.They use these teeth to keep their prey(the animals they eat) from escaping while they can swallow them.Cope's gray tree frogs have teeth in the middle of the roof of their mouth and in the front of the top of the mouth.Once the animal is inside the frog's mouth, the frog uses its eyes to push against the food item to help release it from the tongue, allowing the frog to swallow its food.Ĭope's gray tree frogs have teeth to hold their prey in their mouths:.As a frog sticks out its tongue to capture prey (animal that it eats), the liquid saliva that surrounds the animal becomes thicker and stickier, trapping the animal. When a frog is at rest, the saliva is watery and not sticky.Instead, their saliva is able to convert back and forth between a liquid watery texture and a thick, sticky texture. Their tongues are not "sticky" like a piece of tape.Frog tongues are made of extremely soft tissues, giving them the ability to hold on to the prey.The tongue of a Cope's gray tree frog is long and is attached at the front of the mouth, allowing it to launch as far as possible to capture prey (animals they eat).In humans, it can irritate the eyes, lips, inside of the noes, and open cuts or scrapes.Ĭope's gray tree frogs have tongues that help them capture prey:
