How many families does Anura have?

Are frogs Caudata?
The Caudata are a group of amphibians containing the salamanders (Urodela) and all extinct species of salamander-like amphibians more closely related to salamanders than to frogs.
What’s a baby salamander called?
Most salamanders lay their eggs in water. When the eggs hatch, the baby salamanders look more like tadpoles than salamanders, and are called “salamander nymphs.” The nymphs have feathery gills that extend from the sides of their necks and help the young salamanders absorb oxygen from the water.

Which is the fourth planet in order from the Sun?
Mars, the fourth planet in order from the Sun, is adjacent to the Earth on the outer side. Mars is a planet considered to be the most similar to the Earth and not only in terms of appearance: there is water there, its axis of rotation is similar to the Earth’s, and a day on Mars lasts only 41 minutes longer than on the Earth.
Is the Urodela the same as the Caudata?
Some fossil caudates have not yet been assigned to families. While the terms Caudata and Urodela are usually used interchangeably, some authors have suggested using Urodela to describe only extant forms, while retaining Caudata as the more inclusive group including all known extant and fossil species.
