Amphibians are those amphibians that have both a hard body and soft fleshy skin; they are very diverse in their shape and size. There are around 400 known amphibians including snakes, amphibians that have evolved from reptiles. The name ‘amphibians’ comes from the Greek word ‘amphibious’ and it refers to the ability of amphibians to move freely in water. amphibians are well represented in nature; amphibians are used as workers for collecting food, protecting themselves from predators, and moving from one location to another. In fact, amphibians are used by humans for many purposes.

amphibians are considered to be one of the first forms of vertebrates. They belong to the class of reptiles. The oldest known amphibians are the chordate amphibians which have been dated at about two hundred million years. Another member of this class is the Squamata amphibians which have also been dated at around two hundred million years ago. All these amphibians belong to the Kingdom Prototheria and the order amphibians.

amphibians have become prominent in recent times with the discovery of fossils that show their ancestors to have appeared in the later portion of the Triassic period. The amphibians evolved in the later Jurassic period. During the Cretaceous period, there were a lot of amphibians around. In fact, the dinosaurs were partly amphibians and they had evolved through the evolution of reptile ancestors. amphibians are classified into three main orders:

The order Acrochordon includes several orders including the anole, bulla, rostrum and therein. These amphibians are considered to have evolved from fish. One of the first amphibians to appear on earth was the pterodactyl. It is a fish with a long tail. Later in the Cretaceous period, the order Acrochordon split into two suborders: The Ornithischia and the Saurischia.

amphibians are considered to have evolved from amphibians and fish. The order amphibians has been split into several suborders. The first suborder is the Planktonic. This suborder is composed of the eukaryotic parasites such as the climate and the damsel. These amphibians are present in the fossil record during the Cretaceous period.

The other suborder is the Saurischia. This consists of marine amphibians. There are only six confirmed amphibians from this order. The order amphibians are considered to have evolved from fish. These amphibians are called true amphibians.

The other order is Prototheriaceae. This has about 900 known amphibians. The order is made up of three suborders: Ceratopsidae, Patelliformes and Archosporidae. The amphibians belonging to this order are classified into three main categories: Squamata, Metatherium and uvuloptes. Squamous are the largest of all amphibians and belong to the Metatherium suborder. Little giants are the subspecies of squamata that are found in freshwaters.

We can see amphibians diversified into several species over millions of years. Through fossils we can learn about the relationships among various species. amphibians are diversified into many subspecies because of their ability to move in water and their adaptation to different environments. Studying amphibians is very important for understanding evolution.

There are several theories on how amphibians evolved. One theory is that amphibians are a part of the transitional zone. amphibians are found between amphibians and fish, and they have evolved from fish to cattle. Another theory is that amphibians diversified into animals after the dinosaurs disappeared. A well-known example of amphibians evolving into animals is the salamander.

Another theory on amphibians evolution is that amphibians diversified into amphibians as the ancestors of modern whales and dolphins. These amphibians first developed as nothing more than a tail covered water serpent. Later, they developed wings and were able to breathe air. Thus, the ancestor of the modern whales and dolphins is believed to have been an amphibian. The other theory on amphibians evolution is that amphibians diversified into birds after their ancient ancestor swam through the ocean. Thus, modern birds are a mix of amphibians and reptiles.

The theory on amphibians evolution that is most popular states that amphibians diversified into birds after dinosaurs swam through the waters. Thus, the early amphibians became winged dinosaurs. Over time, the amphibians evolved into reptiles that are found today and their ancestors once were reptiles.

How do we know how amphibians evolved? There are fossils called egg layers that reveal the details of amphibians and reptiles. These fossils help us determine what type of amphibians lived when. amphibians evolved from amphibians and reptiles over time and it is difficult to determine exactly when amphibians and reptiles diversified completely. It is possible that amphibians diversified before dinosaurs evolved in the prehistoric era.
