Amphibians
These cold-blooded vertebrate animals belong to the class Amphibia including over 6,200 species in three groups: caecilians (order Gymnophiona), frogs and toads (order Anura) and salamanders (order Caudata). Amphibians can live both in land and water.

What is a amphibian scientist called?
Zoologists who studies reptiles and amphibians are called Herpetologists
Are all toads frogs but not all frogs toads?
Yes. Did you ever hear the saying 'All Toads are Frogs, but not all Frogs are Toads? Well, that means that Toads are a kind of Frog, and they aren't different. Even though they may look different, if you think about it, they have the same body shape! So think about that saying again and then think about what I just told you.. see what I mean? Write on my message board or in the discussion page if you disagree.
Amphibian is an appropriate name because Amphibian comes from two words, amphi which means double, and bios, which means life. Amphibians have a "double life," one as a tadpole, and one as an adult frog or toad.
Well, both toads and frogs have legs. So, technically they both walk, but it's really more like hopping. Not sure if that's the answer you were looking for, but.. xD
Males walk onto females, and probably they walk when the distance is small.
How long can an axolotl live out of water?
Yes. Just like a fish can be removed from water, but in order for it to live, it needs to be put back in water fairly quickly otherwise it will not be able to breath and will die.
What do amphibians have that fish doesn't?
Amphibians can live in water or land environments, as long as the land environment is moist enough for them, while fish can only live in the water. Their gills are specifically designed to filter oxygen from the water.
Why are amphibians unsuccessful on land vertebrates?
- Amphibians are cold blooded so they cannot regulate temperature.
- They need water for egg lying.
- Their eggs are not covered with shell so they may become dry on land and eggs may be wasted.
- Their skin is so naked, no external covering
How does the three-chambered heart equip amphibians for life on land?
The frog's three-chambered heart more efficiently delivers oxygen to body cells as compared to the fish's two chambered heart. As compared to a four-chambered heart, the frog's three-chambered heart allows blood to bypass the lungs when the lungs are not functioning in gas exchange.
In the three-chambered heart of amphibians, one chamber receives blood from the lungs and another receives blood from THE REST OF THE BODY, INCLUDING THE SKIN. Blood from both chambers then moves to the third chamber, which pumps blood back to the lungs, skin, and rest of the body. This results in some mixing, BUT EXPERIMENTS USING DYES HAVE SHOWN THAT BLOOD PUMPED TO THE LUNGS AND SKIN COMES PRIMARILY FROM THE SKIN AND THE REST OF THE BODY AND BLOOD PUMPED TO THE HEAD COMES PRIMARILY FROM THE LUNGS. BLOOD PUMPED TO THE REST OF THE BODY IS A MIXTURE OF OXYGEN-POOR BLOOD FROM THE REST OF THE BODY AND BLOOD FROM THE SKIN AND LUNGS, WHICH CARRIES OXYGEN. IHOWEVER, in amphibians, the skin is much more important than the lungs as an organ for gas exchange, especially when the frog is under water. THE LACK OF TOTAL SEPARATION OF THE BLOOD IN THE HEART ALLOWS BLOOD TO DETOUR AROUND THE LUNGS WHEN THE FROG IS UNDER WATER. AS COMPARED TO A TWO-CHAMBER HEART, DOUBLE CIRCULATION THROUGH THE HEART RESULTS IN A MUCH HIGHER BLOOD PRESSURE IN THE ARTERIES GOING TO THE BODY.
Why do plankton live in shallow ocean water?
They live in shallow waters because they need the easy access to the sunlight to perform photosynthesis.
Do amphibians breath air and water?
yes they do.
the oxygen in the air is already broken down enough so that the amphibians can breathe it. the process is slightly more complicated in the water. every molecule of water is formed of two atoms of hydrogen and an atom of oxygen. the amphibian swallows the water, and its body decomposes the molecule of water into its components (the process is called hydrolysis). then, the amphibian breathes the oxygen normally. however there are still two atoms of hydrogen left. these two atoms are bound in a reaction of nuclear fusion and form an atom of Helium. the amphibian releases the helium from its mouth, hence the weird squeaky sounds some of them make (frogs)
Toads start mating through mating season. The male has to be a little smaller than the female to mate.
What do baby toads eat and big toads?
No. Horned Toads eat ants mostly, with termites and beetles. They don't eat anything other than insects, so they wouldn't be eating their lizard young.
What are amphibians prey and predators?
Amphibians such as frogs and newts are preyed upon by many creatures such as; certain species of fish, mink, otters, herons...
Snakes and turtles are big predators of amphibians.
That depends on the amphibian, and the part of the world.
The most common predators are snakes, and birds like Storks, Herons, Egrets, Cranes, etc, but most Raptors and Acceptors, will also take them, as will Foxes, Badgers, and most carnivorous or omnivorous animals.
Turtles, Snakes, Racoons, Large Birds, other Frogs, Fish, and People.

What dinosaurs lived in the Jurassic period?
Sauropods (long necks) such as Brachiosaurus and Camarosaurus. Carnivores that lived are Ceratosaurus and some smaller ones.
DON'T FORGET T-REX!!!
Actually, the t-rex was not around until the Cretaceous Period. It is also in the genus of Theropod dinosaurs.
and also allosaurus. allosaurus was the bigest dinosaur that ever lived in the Jurassic besides meglasaurus but i don't think meglasaurus rely existed because i think it was just a load of different dinosaurs put to gethere.
How do amphibians differ from other chordate classes?
Coelmata, three tissue layers, and in the larval state they posses a notochord.
