What is a characteristic of amphibians but not of reptiles?
Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up.
Do all amphibians lay eggs?

What are 3 main characteristics of amphibians?
Modern amphibians are united by several unique traits. They typically have a moist skin and rely heavily on cutaneous (skin-surface) respiration. They possess a double-channeled hearing system, green rods in their retinas to discriminate hues, and pedicellate (two-part) teeth.

One big difference is that reptiles have scales and amphibians don’t. The scales allow reptiles to hold in moisture in their bodies better, which means they can live far from water.
How many different kinds of amphibians are there?
While frogs are quite common there are other kinds of amphibians, including salamanders, toads, and caecilians. In fact, there are over 4,000 different kinds in the world, but less than 20 in the Rocky Mountains. No matter where an amphibian lives or what kind it is, they all share certain things. These common characteristics are what makes them different than other animals, such as reptiles, mammals or birds.
What is the difference between a frog and a reptile?
Amphibians undergo metamorphosis from a larvae to an adult, which means they change their form. For example, a frog begins life as a tadpole before it becomes a frog. In contrast, reptile babies are a copy of the adult, but are just smaller.
How do amphibians communicate?
Amphibians Vocalize To Communicate. Some amphibians, especially frogs, use vocalizations to communicate with each other. The loudest frogs in the world are the Puerto Rican Coqui that creates sounds at 70 – 80 decibels – that is the same noise level as a petrol-driven lawnmower.
What is the meaning of the word "amphibian"?
The word amphibian is based on the Greek word amphibios’ which means “living a double life.”. Their name, therefore, refers to an amphibian’s ability to live on land and in the water at different stages in the life cycle. Most amphibians spend the larval stage in water.
What amphibians have toxins?
Many frogs and salamanders have toxins on their skin which they use to protect themselves from predators. Some of these toxins, such as the toxin of the poison dart frog, are deadly. The most poisonous amphibian is the golden dart frog. These frogs obtain toxins from their diet by harvesting poison from the insects and centipedes they eat. The toxins are stored in glands on the skin and released when needed. Not all amphibians have the deadly toxin. Some just taste bad and cause the predator to foam at the mouth.
What do people think of frogs?
Most people only think of frogs when they think of amphibians. Although frogs make up most of the amphibian group, there are two other amphibians, including salamanders and a worm-like amphibian called caecilians. Amphibians can be found on all continents in the world except for Antarctica and the Arctic.
Why are amphibians ectothermic?
This means that they cannot regulate their body temperature using metabolic means. They are reliant on the environment for warmth because their bodies cannot heat their blood to maintain a constant body temperature.
What are the three main orders of amphibians?
Conclusion. Amphibians have three main orders: they are frogs, salamanders, and caecilians. They evolved from fish, and this is seen in the aquatic larval stage. Gills are used for breathing, but lungs develop as the larva grows, allowing the amphibian to live on land as an adult.
What is the smallest amphibian?
Amphibians come in a range of sizes. The smallest is a frog known as paedophryne amanuensis from New Guinea, which is the size of a housefly. The largest is the Chinese Giant Salamander which can grow to six feet in length and weigh 140 pounds. What are the characteristics that link such diverse animals?
