Why do frogs have slippery skin

Amphibians, like reptiles, are ectotherms. This means that they cannot produce sufficient internal heat to maintain a constant body temperature. Instead, amphibians' body temperature varies, depending on the surrounding temperature. So what does this mean for amphibians? It means that they're responsible for regulating their own body temperature. When it's cold outside and they need to warm up, amphibians often bask in the sun to raise their body temperature.

When it's too cold to even bask, amphibians may brumate. This means they're in a hibernation-like state, but they may have periods of wakefulness and even drink when necessary. When it's hot outside, amphibians spend much of the time burrowing during the day, becoming active only at night. At this very moment, amphibians are facing an extinction crisis.

More than species of amphibians may already be extinct. The greatest threat facing amphibians is habitat loss and degradation. Some toads and salamanders have bad tasting liquids in their skin.

If an animal tries to eat them it gets a mouthful of the bad tasting liquid and lets go. Sometimes the bad tasting liquid can make the animal sick. So many animals will not even try to eat a toad or salamander. Airy Skin Amphibians can breathe through their skin! Uber-fragile and thin skin isn't solely advantageous, however.

One drawback to the very thin skin of most amphibians is easy hydration loss. To make up for this possible issue, amphibians generally remain in habitats that are particularly damp and wet -- think swamps or areas very close to ponds. That way they can help maintain moist and wet skin percent of the time -- without having to deal with excessive loss of water.

Although amphibians generally have the ability to breathe via their skin, that isn't their only means of breathing. Amphibians are equipped with lungs that allow them to breathe as well. This allows frogs to make really loud sounds without hurting their own eardrums! The lungs are capable of doing this by equalizing the pressure differences between the outer surface of the eardrum and the inner surface of the eardrum. Frogs use their eyeballs to swallow. Frogs eat their prey whole and their eyeballs actually sink down into their mouth and push the food down into their throat.

It depends on the species. It can be really hard to tell the males from the females because the sex organs are internal for both males and females. But in many species, the female is larger than the male and the males sometimes have larger toe pads used during mating to grab onto the female. Males also call to attract females and defend their territory, so if you see a frog calling it is probably a male.

The throats of many male frogs are darker than the females. In certain species, it can be easy to tell the difference. In Bullfrogs, the males are larger and have a larger tympanum these are ears-the circles located directly behind the eyes. In many tropical frogs, the males have brighter more vibrant colors.

Frog eggs do not have a shell, so they need some kind of moisture to keep them from drying out until they hatch. Some frogs have come up with amazing ways to keep their eggs wet besides laying them directly in water. There are frogs that lay eggs under leaves above water in damp rainforests and when they hatch the tadpoles fall into the water where they can develop into little froglets.

There are some frogs that carry their eggs on their back and the male Darwin frog actually swallows the eggs and keeps them in his vocal sac until they hatch! Yes, many frogs can change color. Frogs change color to help hide from predators by matching the colors of their surroundings. The also change color to help control their body temperature as some colors absorb more or less light and can cool or warm them up. They use pigment cells called chromatophores to change color. Most frogs cannot completely change their color, instead they change the shade lighter or darker of their basic color.

Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin.
