Which one of the following has the embedded sclaes in the skin?

Options

A. Siren
B. Triturus
C. Uraeotyphlus
D. Xenopus

Answer

To solve the question "Which one of the following has the embedded scales in the skin?" we need to analyze each of the options provided:

1. **Siren**: Siren is a genus of aquatic salamanders, characterized by their elongated, eel-like bodies and small vestigial forelegs. They do not have embedded scales in their skin.

2. **Triturus**: This genus includes newts, specifically the crested and marbled newts found in Great Britain. Like Siren, Triturus does not have embedded scales in their skin.

3. **Uriotephilus**: This is a family of Indian caecilians, which are limbless amphibians. Their skin is smooth and slimy, but importantly, they do have small scales embedded in the dermis. This makes Uriotephilus a strong candidate for the answer.

4. **Xenopus**: Commonly known as the clawed frog, Xenopus is a genus of aquatic frogs native to sub-Saharan Africa. They do not have embedded scales in their skin.

After analyzing all the options, we conclude that the correct answer is **Uriotephilus**, as it is the only one that has embedded scales in the skin.

### Step-by-Step Solution:
