Your comments: What was the best part of Blue Planet?

Blue Planet II splashed onto our screens last night - and showed us some amazing scenes.

It took four years to make and used the latest technology to get seriously close to the creatures underwater.

There were plenty of incredible moments - so we want to know your favourite!

My favourite part of Blue Planet II was when the tuskfish was whacking the clam against the rock to break it open!

I enjoyed the dolphins and the false killer whales. At first it looked like they were going to kill each other but instead they were old friends and I did not expect that at all.

I liked the tuskfish because it was really determined to get its food and it seemed very smart.

Anouk, England

I liked the bird who left it to the last minute before escaping with the fish.

The female fish that turns into a male when it gets to a certain age!

My favourite bit was the bottle-nosed dolphin.
