Your sentence is almost correct but has a small error in the word 'blabber'. The correct word should be 'blubber'. Here's the corrected sentence:
The Arctic fox has thick fur, and the walrus has a thick layer of blubber to keep warm in the extreme cold.
Let's break it down:
- Arctic fox has thick fur: This part is correct. The Arctic fox uses thick fur to stay warm.
- Walrus has a thick layer of blubber: The word 'blubber' means a thick layer of fat under the skin, which many cold-weather animals have to keep warm.
- Comma usage: We add a comma before 'and' because it connects two complete ideas (clauses).
