The gastric frog is gives birth to its young through its mouth.
Frogs absorb water through their skin so they don't need to drink.
Frogs can lay as many as 4,000 eggs in frogspawn.
Some salamanders have poisonous skin.
Newts have the ability to regenerate limbs, eyes, spinal cords, hearts, intestines, and upper and lower jaws!
The male midwife frog wraps the string of eggs around his legs and keeps them with him, guarding them from predators until they hatch.
Salamanders and newts must stay near water. If they get too dry and hot, they’ll die.
The eyes and nose of a frog are on top of its head so it can breathe and see when most of its body is under the water.
The wood frog buries itself and goes into a deep hibernation, its breathing and heartbeat stop, and as much as 65% of the water in its body gradually turns into ice.
Salamanders and newts are carnivores. They move slowly so they have to catch slow-moving prey like worms or snails.
Many frogs can jump 20 times their own height.
Female newts lay one egg at a time on a specially selected piece of pond plant. She sniffs the leaf to make sure it has the right cellulose amount and then after laying one egg closes the leaf around it with her back legs and glues it shut over the egg.
A frog’s ear is called tympanum and it is located just behind the eye. If the tympanum is larger than the frog’s eye, it is male; if it is smaller, it is female.

When mating season comes, the male newt secretes a strong pheromone to attract a female. Then, it does a little dance by swinging its tail in the air.
Even though axolotls are forever in their larval stage, they can still reproduce.
Newts hibernate in winter usually under logs and stones and in rubble piles.
Axolotls, can be made to undergo metamorphosis. A shot of iodine makes them completely transform, looking like tiger salamanders but with spots instead of stripes.
