Question

Large sized scales fully extending from side to side on the belly, are characteristic of

• A. Rat snakes and cobra
• B. Cobra and python
• C. Python and krait
• D. Krait and seasnake

Answer 1

The correct option is D Krait and seasnake

One of the characteristic features of all reptiles is the presence of scales or scutes on their body. Unlike scutes which are bony structures as is seen on crocodiles, a shell of turtles, the scales are small, hard plates composed of the protein keratin and develop from the epidermis. Scales usually vary in size, with larger scales covering parts exposed to physical stress. Most snakes like krait and sea snake have extra broad scales on the belly, each scale covering the belly from side to side. However, in Xenodontinae and viperine snakes the scales on the belly are more like flattened plates and arranged in a single regular row.

So, the correct answer is option D.
