Amphibian, any of roughly 8,100 vertebrate species known by their ability to exploit both aquatic and terrestrial habitats. The name amphibian, derived from the Greek word meaning 'living a double life,' reflects this dual life strategy, but some species are permanent land dwellers, and others are completely aquatic.

Many amphibians—like this Ceratophrys cranwelli—exhibit biofluorescence.. Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia.In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals).

Lay Eggs in Fresh Water (most - but not all - amphibians need fresh water in which to lay their eggs.) Skin Breathing (an amphibian's skin is rich with capillaries - thin blood vessels that allow gas exchange between the animal's blood and the surrounding air or water.) Skin Without Scales, Feathers or Hair.

The life cycle of amphibians has three stages:. Egg Stage: Amphibians lay eggs, usually in water. Larval Stage: Larvae (e.g., tadpoles) live in water and breathe through gills. Most species undergo a metamorphosis into an adult form. Adult Stage: Adult amphibians typically live on land and breathe with lungs and through their skin. There are exceptions, like the axolotl, which has lungs, but

Amphibians. Amphibians are a class of cold-blooded vertebrates made up of frogs, toads, salamanders, newts, and caecilians (wormlike animals with poorly developed eyes). All amphibians spend part of their lives in water and part on land, which is how they earned their name—"amphibian" comes from a Greek word meaning "double life.".

The official class of amphibians is Amphibia. Amphibians are vertebrates that require water to survive, are cold-blooded, and spend time both on land and in water. Though other animals only live on land or in the water, amphibians have the unique ability to thrive equally in both. Amphibians cover over 6,000 different species across the […]

All amphibians are cold-blooded animals and most metamorphose from a juvenile to an adult form. They cannot generate their own body heat, instead relying on the temperature of their environment to help them keep warm or cool enough to survive.

The three living orders of amphibians vary greatly in size and structure. The presence of a long tail and two pairs of limbs of about equal size distinguishes newts and salamanders (order Caudata) from other amphibians, although members of the eel-like family Sirenidae have no hind limbs. Newts and salamanders vary greatly in length; members of the Mexican genus Thorius measure 25 to 30 mm (1

The word "amphibian" is Greek for "both kinds of life," and that pretty much sums up what makes these vertebrates special: they have to lay their eggs in the water and require a steady supply of moisture in order to survive.

Amphibian Facts. Amphibians are cold-blooded which means the temperature of their body changes when the temperature of the air or water around them changes. Amphibians are vertebrates like mammals, birds, fish and reptiles. Vertebrates are animals that have a backbone. Amphibians can live on land and in the water.

The First Fact: Amphibians have permeable skin. One of the most remarkable characteristics of amphibians is their permeable skin. Unlike other vertebrates, amphibians can directly absorb water and oxygen through their skin. This ability allows them to breathe and live both in water and on land.
