Amphibians

They had little competition from other land dwellers

Lobe-finned fish, like lungfish and the coelacanth. Their fins have the makings of all the bones needed for a leg or arm, and some swim using movements that resemble walking, so the foundations were there already. The adaptations were made in water and happened to be useful on land too. ^^

The vast majority of amphibians lay eggs with the exception of one particular species of frog, the Asian Fanged Frog (Limnonectes larvaepartus), which is the only known amphibian species that gives birth to live tadpoles.

Amphibians are part of the kingdom Animal. Same worms and humans.

To narrow it down, they are part of the Phylum Chordate.

Yes.

Amphibians without tails are frogs. Frogs make up 90% of amphibian species. Frogs belong to the order Anura.

look it up in your biology book!

Amphibians are distinctive because they can live in water and on land.

They do not.

Instead, they feed on insects, grubs, slugs, worms, and other invertebrates like other amphibians do.

But as tadpoles, the feed on plants.

They have four: Gills, lungs, tongue, and skin.

Salamander? It's a type of amphibian but I don't know if that's what you are looking for. If it isn't, sorry.

Under my recent research done in cairo, egypt, i have discovered that indeed the poison in toads is potent enough to kill even the largest of crocodiles. This venomous posion can even kill a T-REX! trust me, im a doctor

well amphibians are creatures that live in wetlands or live close to water. like frogs and toads

Yes, cockroaches will be eaten by frogs. A frog is one of the many natural predators of the cockroach.

While reptiles generally thrive in temperate and warmer climates, there are certain species that have adapted too much colder environments. Temperature can also determine whether a reptile is diurnal or nocturnal. In other words, temperature affects the eating habits of reptiles.

A gilled, aquatic larval stage and an air-breathing, terrestrial adult stage Gelatinous eggs with no hard shell or membrane Permeable skin, no protective skin covering (such as fur, feathers or scales) No claws or nails on their toes

There are several different amphibians that have adapted enough to survive in the desert. Most of the amphibians are frogs or toads of one kind or another.

In amphibians, syngamy occurs in the external medium (water) i.e. outside the body of organism while in reptiles, syngamy occurs inside the body of organism.

amphibians breathe through their skin. that's why its so important that if you have amphibians, you should always make sure that their environment is clean.

beause amphibians were the top species during the Carboniferous Period

Characteristics that resctrict amphibians to water include:

1) They breathe through their skin, which needs to be moist.

2) Their eggs are fertilized via external fertilization, which requires water.

3) They have gills which only functions in water.
