Amphibians include animals such as frogs, caecilians, and salamanders. They are characterized as cold-blooded tetrapods ( four limbs ).Most Amphibians undergo metamorphosis from a juvenile water-breathing form to an adult air-breathing form.
Amphibians are ecological indicators.They live both in the water and on land.
For the purpose of reproduction most amphibians require fresh water.
Since they can live either on land or in water they must have both lungs and gills, or rudimentary gills. They don't have constant body temperature but have moist skin and their temperature is the same as the ambient temperature.
Amphibians, like frogs and salamanders, have moist skin and are ectotherms, meaning their body heat matches the heat of the environment around them. They do not have any scales, and they must live in moist environments for reproductive and respiratory means.
Amphibians, like frogs, toads, and salamanders, have moist skin and are ectotherms, meaning their body heat matches the heat of the environment around them. They don't have any scales, and they must live in moist environments for reproductive and respiratory means. Amphibians were the first tetrapods.
1.Scales are absent.
2.Gills and lungs are for respiration.
3.They have necessitating membrane.
4.They have three chambered heart.
5.They are cold blooded.
6.They lay eggs.
7.They live either on land or water.
The four characteristics of amphibians are characteristics any animal must have to be classified as an amphibian. These include: the animal must be a vertebrate and have a backbone, the animal spends much of its life in water as well as on land, the animal is cold blooded, and the animal does not have scales but have permeable skin. Animals that are amphibians also go through metamorphosis, as a frog goes from an egg to a tadpole to a frog.
1. Amphibians are cold blooded.
2. Amphibians larvae mature in water and breathe through gills.
3. Adult amphibians breathe through lungs and skin.
4. While adult amphibians spend part of their time on land, they still need to spend time in water due to the scaleless, moist nature of their skin. Without a water source they would become dehydrated and die.
There are many characteristics of a amphibians. The most common include being cold-blooded, having a back bone and live on both water and land.
2) Amphibians are cold-blooded or exothermic animals. Unlike warm-blooded animals, which regulate their body temperature internally, amphibians derive heat from outside their body.
3) The skin is smooth, thin, hairless, porous and rarely scaled. The skin contains both mucus glands and poison glands.
4) A bone endoskeleton with varying numbers of vertebrae; ribs present in some, absent or fused to vertebrae in others.
5) A smooth, thin, porous skin containing both mucus glands and poison glands.
6) Four limbs which may vary in size with the forelimbs of some being much smaller than the hind limbs; some are legless.
7) Limbs have varying numbers of digits and webbed feet are often present; no true nails or claws.
8) The mouth is usually large with small teeth in upper or both jaws; two nostrils open into the anterior part of the mouth cavity.
9) Respiration is accomplished either separately or in combination by lungs, skin, and gills; some larval types possess external gills and these may persist throughout life.
10) A three-chambered heart consisting of two atria and one ventricle.
1, can live under water breathing through skin.
2, adult can live on land as they have lungs.
3, moist soft skin.
4,eggs laid in water.
Yes. Some alien races have animal characteristics (i.e. mammals, reptiles, amphibians, insects, arachnids, gastropods, reptomammals, reptavians, crustaceans, avians, mammavians, etc.).
amphibians have skin that are slimey and can live in and and out of water
Most evolutionary scientists today do not think that amphibians evolved from the lungfish. They do share some characteristics, but the lungfish has no hint of legs.
Any other characteristics than what? They are cold-blooded, they start their lifecycle in the water and at the onset of adulthood move to dryland. They are mainly carnivorous, eating small water creatures and insects.
They don't really. They hunt for food in water, but that's about it. It takes plenty more characteristics to make an amphibian.
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.
Color, sounds, poisons, are all factors that some amphibians have. Some just aren't seen due to camouflage and do not have or need these traits.
some amphibians live in the water for shelter and some could live on land too.
Only toads and frog are known to be hopping amphibians.
Mammals, reptiles, amphibians, birds and fish are the five groups of animals.
All amphibians are carnivores. Amphibians lack the digestive system for eating plants. Amphibians can accidentally some plants and they will mostly not harm them, and just pass out of their bodies.
Most amphibians are asymmetric. Although some appear to be symmetric.
