If your kids have always been fascinated by the sea and all the creatures in it, this could be the book for you.

Today you can pick up the fifth book in the Disney Wonderful World of Knowledge series.

Cut out the coupon, below, pop along to your nearest participating retailer, and for just £2.99 you can delve the depths of the ocean in Wonders Of The Sea.

It is full of amazing facts.

Did you know, for instance, that if you had an aquarium with flounder in it, and you lined it with chess boards, the fish would quickly change colour to match the background?

You could also use the Wonders Of The Sea book to discover which poisonous fishy delicacy requires specially-trained chefs in Japan to cook it, or find out how the moray eel cleans its teeth.

We asked Chris Donkin, the manager of SeaQuarium in Weston-super-Mare, what he thought of the book.

He said: "I thought the book was fantastic. I think it is good for adults as well as kids – full of fishy facts and information I didn't know. We get lots of children here – they love fish.

"I think they like the colours and the movement, the way they glide. They are so graceful when they move through the water. We have sealife here from around the world. I think it is important to learn about it all – we are all sharing the same planet. There is so much we don't know about what is in our seas and rivers. No week goes by when a new species is not found."

Next week you can collect the following book in the series, called Great Travellers and Explorers.
