Better sentences you can use:
Present tense: With its super nose, an echidna senses a moving bug and grabs it.
Past tense: With its super nose, an echidna sensed a moving bug and grabbed it.
Why these are better (easy steps):strong>
- 'With its super nose' is fine — it tells how the echidna noticed the bug.
- Use 'senses' (or 'sensed') instead of 'feels' if you want to say it notices the bug using its nose. 'Feels' is okay, too.
- 'A moving bug' describes the bug that was moving. You can also say 'a bug moving nearby' to make it clearer.
If you want, I can make the sentence sound fancier or simpler for reading aloud.
