My new book, Aurora and the Popcorn Dolphin has just come out in Ireland and the UK and features a very special dolphin called Click. I’ve always been fascinated by dolphins and whales. When I was nine I tried to teach myself how to speak humpback whale by listening to a plastic record of their amazing song. Strange but true! The record came attached to a copy of National Geographic magazine and it was one of my prized possessions.
Every day after school I’d shut myself in my room and wail and moan like a humpback. My mum used to rush into my room, thinking I was sick. If you’ve ever heard a humpback whale singing you’ll know what I mean.
There are lots of dolphins in the waters around Ireland where I live and I’ve been lucky to see them on many occasions. I’ve seen whales too, in both Ireland and New Zealand.
I had so much fun researching this book and I learned a lot about sea mammals along the way. I used some of my (and Rory’s) favourite dolphin and whale facts to write the quiz below. Do try it!

3/ A Like all mammals, whales and dolphins have to breathe air. Whales can stay underwater for up to 90 minutes, dolphins need to breathe every 10 or 15 minutes.
