Yes — your sentence is almost correct, but we can make it clearer. A good corrected version is:
The crocodile seizes its prey with its powerful jaws.
Or an easier way to say it:
The crocodile uses its powerful jaws to catch prey.
Why change it?
- The crocodile is who we are talking about (the subject).
- Seizes is the action word — it means "grabs".
- Prey means the animal the crocodile eats (the object).
- Adding its before prey or powerful jaws shows that the prey and the jaws belong to the crocodile.
You can keep the exclamation mark if you want the sentence to sound excited, or use a period if you want it calm.
