Their unique ability to live both on land and in water makes them interesting pets.

Amphibian definition

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).

• Cold-blooded means that an amphibian can't generate its own body heat. Instead, their temperature varies with the temperature of the surrounding environment.
• Vertebrate means that amphibians are a type of beast with a backbone or spine.
• Aquatic means in water. Amphibians begin their life living underwater, breathing through gills and swimming with tails.
• Terrestrial means on state. At a later stage of life, amphibians develop lungs and legs and move out of the water to alive on land.

Probably the best-known example of an amphibian is the frog. You probably know that frogs brainstorm life as tadpoles: little fish-similar creatures that breathe through gills and swim effectually with small tails.

You lot'll also know that frogs don't stay tadpoles forever. They develop legs and somewhen hop onto dry out land, where they breathe through their lungs every bit nosotros do.

Characteristics of Amphibians

Conspicuously, how amphibians look varies depending on the stage of their life.

A polliwog looks completely different from a frog, for example.

Only there are some characteristics that are generally consistent across near amphibian species.

• Amphibians take moist bodies. If you picked upwards a ophidian (which is not an amphibian) it would feel very dry. Contrary to popular belief, snakes aren't "slimy". Notwithstanding, if yous picked upward an amphibian – such equally a frog – its peel would experience wet and slippery.
• Amphibians don't have scales. Taking the snake instance over again, if you looked closely at a snakes torso, you'd see lots of tiny plates, chosen scales. Scales are what fish and reptiles have instead of skin. They don't have scales, they take smooth pare.
• Amphibians will die if their trunk dries out. The reason they have moist bodies and smooth peel is that they need it to survive. Amphibians accept a special skin that is able to absorb water and oxygen, stopping them from getting dehydrated. This is why, fifty-fifty once they get-go living on land, amphibians usually alive shut to h2o.
• Some amphibians can "aestivate". This is a special ability that allows sure types of amphibian to enter a fallow country if conditions go too hot and dry. They then return to normal once cooler, wet conditions return.
• Some amphibians are poisonous. Poisonous amphibians release toxic chemicals through their skin to impairment and scare abroad predators.
