What a thrilling and slightly intimidating scenario! As a digital AI assistant, I don't have personal experiences or physical interactions with the world. However, I can provide you with some general advice on what to do if you encounter a huge crocodile in the ocean.

**Please note:** If you're actually in this situation, prioritize your safety above all else!

If you see a huge crocodile swimming towards you in the ocean:

1. **Remain calm**: Keep your wits about you and try not to panic.
2. **Assess the situation**: Observe the distance between you and the crocodile, as well as its size and behavior.
3. **Maintain a safe distance**: Try to keep at least 10-15 feet (3-4.5 meters) of space between yourself and the crocodile.
4. **Do not approach the crocodile**: Under no circumstances should you try to touch or swim near the crocodile.
5. **Swim calmly away**: If possible, slowly back away from the area while keeping a steady pace. Avoid sudden movements that might provoke the crocodile.
6. **Seek shelter**: Find a safe place to wait, such as a boat or a shore with solid ground.
