5.      How do frogs breathe? What is respiration?
The frog is covered by a soft, thin, most skin composed of two layers: an outer epidermis and an inner dermis. The skin does not merely protect the frog but helps in respiration. Lots of blood vessels runs throughout the frog's skin. Oxygen can pass through the skin and enter directly into the blood. When a frog goes under the water, all its respiration takes place through the skin. Oxygen is obtained directly from the water. The frog doesn't breathe through its skin alone. Adult frogs have paired, simple, saclike lungs. Like humans, air enters the body through two nostrils, passes through the windpipe, and is received by the lungs. The actual breathing inside of the body is different, however. In humans breathing is aided by the ribs, the diaphragm, and the chest muscles. The frog has no ribs or diaphragm, and its chest muscles are not involved in breathing. A frog may breathe by simply opening its out and letting air flow into the windpipe. However, it may also breathe with its mouth closed. The floor of the mouth is lowered, causing the frog's throat to "puff out." When the nostrils open, air enters the enlarged mouth. Then, with nostrils closed, the air in the mouth is forced into the lungs by contraction of the floor of the mouth.

6.      What are their predators? Are there any diseases that affect them?
African Dwarf frogs can die from diseases and can be eaten by predators. Two diseases that can occur are bloating and fungus. Fungus is when the frogs may lose their limbs. They usually recover but not always. Bloating is when frogs eat too much and get full of liquid. They may look like it's going to blow up. Some of their predators are the African clawed frog, snakes, lizards, birds, some kinds of fish and other frogs.

7.      How do Dwarf African frogs mate?


8.      Why is a toad's skin slimy?
First you need to know that a toad's skin is pretty dry except for the poison. The poison is slimy, so that's what makes the skin feel slimy to the touch. The toads have poison glands behind their eyes. The glands have a job of putting the poison all over the body. When all the poison is over the toad and its foe lunges and tries to bite it, it is able to get away. Even though the poison is not strong enough to hurt humans, you should still wash your hands because it might urinate on you.

9.      What is the life cycle of a frog?
Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn. Several thousand are sometimes laid at once. A jellylike covering protects the egg. Only a few actually develop into adults as many of the eggs are eaten by other animals. Anyway, the cell inside the egg eventually splits into two which split into four and so on until there are many cells in the egg. The mass of cells in the egg forms an embryo. Organs and gills begin to form. The embryo lives off of its internal yolk for about 21 days. Then the embryo leaves its jelly shell and attaches itself to a weed in the water. This quickly becomes a tadpole or baby frog. The tadpoles grow until they are big enough to break free into the water. This can take from 3 days to 3 weeks depending on the type of frog. They eat algae. The tadpole has a long tail and lives in the water. After about five weeks, the tadpole begins to grow hind legs and forelegs. Bulges appear behind their heads where their front legs are growing. Their tails become smaller. Lungs begin to develop, preparing the frog for its life on land. They wiggle to the surface to breathe in air sometimes. The tail becomes larger and makes it possible for the tadpole to swim around and catch food. They eat plants and decaying animal matter. Some tadpoles eat frog eggs and other tadpoles. The tadpole becomes more froglike over time. They shed their skin and lips. Their mouth widens, and they lose their horny jaws. The tail becomes much smaller, and the legs grow. The lungs are almost functioning at this point. Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land, with occasional swims. It begins to eat insects and worms. It eventually finds a mate. The female lays the eggs, the male fertilizes them and the whole process begins again.

10.     What is the life span of African Dwarf frogs?

11.     How do you tell the difference between male and female African Dwarf frogs?
Male frogs usually have black markings on their arms and will be somewhat smaller. Also males make noises.

12.     What is unique about a frog's body structure? Why are they shaped the way they are?
A frog's body structure is unique many ways and there for many reasons. A frog is unique because they have two bulging eyes, strong, long webbed feet that are adapted for leaping and swimming, and smooth or slimy skin (generally frogs tend to like moister environments). Their body structure is also unique because frogs can have different kinds of eyes; round pupils; vertical pupils (like cats); horizontal pupils; and heart shaped pupils. They also have a special tongue that snaps to get food. When a frog swallows, its special eyeballs go down into its head to push down its good into the throat. Talk about unique! Frogs have two kinds of teeth: (only on their upper jaw) maxillary and vomerine. They are there to hold their food while they ready their eyeballs to push it down. Frogs have holes in the side of their head instead of ears. You can't make fun of them for having big ears! Different species of frogs have feet for different things. Climbing, flying, swimming and digging are those. Frogs are the farthest jumpers in the world with their unbelievably strong legs. Frogs have special skin too for breathing and drinking. They have to stay by water because their skin needs to stay moist, or they will stop breathing. That is what is unique about a frog's body structure and why it is there.

13.     What makes an amphibian an amphibian?

14.     What do Dwarf African frogs eat?
They are scavengers and will eat most anything they can fit into their mouths. They find their food by smell and touch. In captivity you should feed them brine shrimp, krill, shrimp pellets, and Tetra Reptomin sticks. Avoid overfeeding them. Only give them as much as they can eat in fifteen minutes.

15.     Can frogs spread diseases to humans? If so, which ones?
Yes, there are diseases that amphibians can get that can be passed to humans. Tape worm cysts are one of the diseases that can be transmitted from frogs to humans. Diseases passed from amphibians to human are called zoonoses.  Salmonella, which is a disease that people can get by eating raw cookie dough, is a common disease passed from amphibians to humans. The way these diseases are transmitted are by not washing your hands after handling one or by kissing your frog. Those are frog diseases that humans can catch from frogs and other amphibians.

16.     What is the most common frog? Why is it so common?
17.     Compare a poison dart frog to a Dwarf African frog.
19.     How do frogs communicate?

20.     Compare a leopard frog to a Dwarf African frog.
Leopard frogs are native to North America while Dwarf African frogs are native to the Congo in Africa. Leopard frogs have brown or green skin with dark spots and yellow ridges along the sides of their backs. They can be between 2 to 4 inches in length. Dwarf African frogs, on the other hand, are very small frogs with webbed feet. The females are bigger than the males. The males have darker, bumpier skin and a prominent white bump on their forelegs. Both frogs are carnivorous and active at night. Leopard frogs live in marshes, swamps, ponds, and meadows. They spend most of their time int eh damp undergrowth. African Dwarf frogs live in fresh water and stay in it. They only come up to the surface for air.

21.     Why is a salamander an amphibian? What characteristics make it a salamander?

22.     What do African Dwarf frogs eat, and how do they catch their food?
They eat frozen bloodworms or blackworms and brine shrimp. They smell out their food.

23.     How do frogs hear without outer ears?
Although frogs lack an outer ear, they hear very similar to us. Frogs have an eardrum, a middle ear, and an inner ear. Without the outer ear, it is just less likely to catch sound waves. There is another difference between a frog and a human's hearing. They can sense vibrations with their lungs. Frogs can do this because their lungs are right under the skin so when vibrations hit the side of a frog it feels it. That is how frogs hear without an outer ear.

24.     What is burbling? Why do Dwarf African frogs do it?

25.     Why do Dwarf African frogs stay in water when other kinds of frogs go on both land and water?
Dwarf African frogs live underwater for many different reasons. They can breathe through their skin and can find food underwater. They have no need to get out of water. Some frogs live in trees like the tree frog and can find food in different areas other than water. Some are permanently aquatic, and still others spend their life in underground burrows coming up only to feed or breed. Most frogs are found in moist areas and like the Dwarf African frog have no need to go on land.  

26.     How big can a Dwarf African frog get?

27.     How do Dwarf African frogs eat?
Dwarf African frogs generally eat food that sinks to the bottom of the tank. They seem to be visual hunters, but it's likely that they can also detect food by scent. In fact, it's not uncommon for them to snap at each other when searching out their food! It looks a lot as if they have the hiccups, but they are just snapping around trying to find something good to eat. They feed by striking suddenly at their prey. They don't chew their food but gulp it down whole. These frogs will eat huge amounts of food for their size. Care must be taken not to over feed them.
