Aquatic amphibians will eat bugs, other amphibians including tadpoles, fish and small aquatic organisms.
There is only one frog species known that is actually a vegetarian: The Brazilian Tree frog eats fruits and berries! Most tadpoles eat plants and algae in the water. They are important grazers in aquatic systems because they help with nutrient recycling and control algae populations, which help to maintain the health of freshwater ecosystems.
Sometimes tadpoles will eat each other, especially if food resources are low. Some tadpoles eat insect larvae and tiny organisms that are found in the water. Although many species are only active at night, there are some that are active during the day. Amphibians are usually active at night because they are harder to see and can avoid being eaten.
Poisonous amphibians that are brightly colored are often active during the day. Bright colors on an animal will warn predators that they are poisonous, so they do not have to worry about predators.
Yes, there are many amphibians that hibernate. Amphibians do not like extreme temperatures. During the cold winter months in non-tropic areas, most amphibians will either hibernate in the mud at the bottom of water or dig down into the ground to hibernate. Some amphibians stow away in cracks in logs or between rocks during the winter. They slow their metabolism and their heartbeats down and survive off stored body reserves throughout the winter.
There are some frog species that can even survive freezing temperatures by maintaining a high level of glucose in their blood that acts like antifreeze. Some of the frog will actually freeze, like their bladder, but their blood and vital organs do not freeze.
The heart can stop beating and the frog can stop breathing, but it when it thaws out, it will still be alive. No, only some species of amphibians are poisonous. Usually they are brightly colored to warn predators of their toxic nature. Most amphibians secrete chemicals from their skin to make them taste icky to predators or make it difficult to handle them. These secretions can be slippery or can be sticky and irritating to the skin.

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. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog. Other frogs actually secrete a waxy coating that they spread across their body to help retain moisture in areas that have high temperatures or if they are active during the day.
The white stuff is secreted toxins. Some salamanders and frogs or toads secrete noxious chemicals as deterrents to predators. These secretions can be relatively mild to highly toxic.
If you see white stuff on an amphibian skin, do not touch it! Yes, frogs have lungs like we do and if their lungs fill with water, they can drown just like us. Frogs can also breathe through their skin. They need to keep their skin moist to be able to breathe through their skin, so if their skin dries out they are not able to absorb oxygen.
They use their skin to absorb oxygen when underwater, but if there is not enough oxygen in the water, they will drown. To not waste all the nutritious protein found in their skin. Frogs shed their skin periodically like most animals, but they do not slough it off and leave it behind. Frogs actually push the shedding skin into their mouth and eat it. This is the ultimate way to recycle all the components they used to produce their skin.
So they can see behind them and to the sides without having to turn their head around. The large eyes are set far apart from each other and protrude out of their heads to give them an almost degree view of their surroundings. This helps them see potential predators and prey to either make a quick escape or catch their dinner. Can frogs see underwater? Yes, frogs have a third eye lid that covers their eyes so they can keep them open underwater.
