Can you recommend a non-fiction book about ocean/sea creatures?

My ds7 is really interested in under water stuff. I'm finding it quite hard to find a decent book that he'd like that's not too babyish and not a massive academic tome.

He loves great photography but also facts and diagrams etc. I've been trawling Amazon but can't find anything is really looking for. There's an usborne one but it doesn't seem to be available.

Any ideas?

Dorling Kindersley Eyewitness childrens reference books are good. Don't know if they still do the "Look Closer" guides, they were v good too.

Everything Dolphins by National Geographic Kids is good

DS just brought this home from the school library. He loves it.
