what is amphibians

Amphibians are cold-blooded, vertebrate animals that have an aquatic phase of life (spent in water, breathing through gills) and a terrestrial phase of life (living on land, breathing with lungs). As the larva grows into its adult form, the animal's lungs develop the ability to breathe air, and the animal can live on land. The skin greatly helps in regulating the body temperature but also makes them vulnerable to dehydration. Amphibians have scale-less skin that is very delicate and moist. Living examples include frogs, toads, salamanders, newts, and caecilians. They live close to water sources in order to dampen their skin. In high temperatures, dehydration will lead to death. Among other things, animals in the Chordata phylum have a backbone. However, there are many exceptions. They are among the most fascinating (and rapidly dwindling) animals on earth. Amphibians are a class of cold-blooded vertebrates made up of frogs, toads, salamanders, newts, and caecilians (wormlike animals with poorly developed eyes). Amphibians are animals that belong to the phylum Chordata. amphibian definition: 1. an animal, such as a frog, that lives both on land and in water but must produce its eggs in…. Amphibian definition. Members of this animal class are frogs, toads, salamanders, newts, and caecilians or blindworms. The adults return to the water to court and ultimately lay eggs. Frogs, toads, and salamanders are all amphibians. Life as an Amphibian The typical life cycle of amphibians is a larval stage that lasts a few months, followed by a brief metamorphic period, then a long, multiyear life on land.

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia.All living amphibians belong to the group Lissamphibia.They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems.Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. An amphibian is any non-amniotic (lacking eggs with a shell), cold-blooded, tetrapod animal that spends at least part of its time on land. Amphibians are cold-blooded, which means that they are the same temperature as the air or water around them. 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.” Amphibians are animals that live part of their lives in water and part on land. Amphibians are cold-blooded vertebrates (vertebrates have backbones) that don’t have scales. An amphibian is a cold-blooded vertebrate animal that is born in water and breathes with gills. They are vertebrates and are also ectothermic; they cannot regulate their own body heat, so they depend on sunlight to become warm and active. They live part of their lives in water and part on land. Amphibians are a class of animal that represents a crucial evolutionary step between water-dwelling fish and land-dwelling mammals and reptiles. There are more than 4,000 different kinds of amphibians. Learn more.
