Question

Give three structural differences between a frog and a lizard?

Answer 1

Hint: Organisms that live a dual life are amphibians. They can survive both on land and on the sea. They have skin that is brittle and needs moisture. Eggs are often laid in the water by amphibians, and their young have gills to live in the water. Only when fully grown do they venture onto land.

Complete answer:
The following are the differences between a frog and a lizard-

Frog	Lizard
Frog is an amphibian. Animals that can live on land and in water are amphibians, which are distinguished by damp glandular skin, gills, and a lack of scales.	A lizard is a reptile and reptiles have scale-covered skin, breathe air through their lungs, and lay hard-shelled eggs on the ground.
They are species that are cold-blooded.	There are species that are cold-blooded. (Birds are actually an exception).
Fertilization is an external type.	There is internal fertilization.
They can breathe through the gills and the lungs as well.	They're breathing through their lungs.
The skin is delicate and extremely porous.	The skin is scaly, rough, and dry.
Frogs, toads, salamanders, and newts are some examples of amphibians.	Alligators, crocodiles, lizards, snakes, turtles, and tortoises are all examples of reptiles.

Note: Reptiles and amphibians have a number of characteristics that differentiate them from each other but they belong to the same class, reptilia, and they also share many anatomical and physiological characteristics. The same phylum and subphylum belong to reptiles and amphibians. They are ectothermic and are used to defend themselves from predators using camouflage. That is why there was no distinct zoological classification for the two in earlier times.
