What are the essential signs of a toad and a lizard?

So, toads belong to the family of tailless amphibians. Their body length can be different from twenty millimeters to two hundred and fifty millimeters. Their tongue is narrow and large enough. The body is usually wide and rather heavy. The skin is covered with such wart tubercles.

Lizards belong to the suborder of reptiles (squamous order). It is also worth mentioning that most lizards can discard part of their tail. They have no more than two sacral vertebrae.
