About the author

In their review of my first book, Poseidon’s Steed, the Economist called me “The aptly named Helen Scales” and I guess they’re right. I do have a bit of a thing about fish (get it?).

Across the airways and in print, I’m noted for my distinctive and occasionally offbeat voice that combines a scuba diver’s devotion to exploring the oceans, a scientist’s geeky attention to detail, a conservationist’s angst about the state of the planet, and a storyteller’s obsession with words and ideas.

I have a Cambridge PhD and a monofin, I’ve drunk champagne with David Attenborough and talked seahorse sex on the Diane Rehm show. I spent four years (on and off) chasing after big fish in Borneo and another year cataloguing marine life surrounding 100 Andaman Sea islands.

These days I write books and articles, I make podcasts and radio, travel the world in search of stories, and do my best to spend as much time as I can in the sea as a scuba diver, free diver and rookie surfer. I’m a fellow of the Royal Geographical Society and a member of the steering committee for the Museum of Curiosity. I’m also a proud aunt, I sew dresses, grow organic vegetables, put on high heels and dance Argentine tango, play piano, sing in the shower, and make a mess in a printmaking studio.

One of my new favourite books! Alexandra gifted it to me despite being scared that it would be a redundant read since I also have the Oceanarium book, but they are so complementary (and this one is even prettier in my opinion). Rather than focusing on being complete, this book explores less known species like the strawberry squid or the puffadder shysharks which I had never heard of, and provides really interesting facts in a light fun way. This book would be adapted and engaging for kids and yet I thoroughly enjoyed reading it. Would recommend to anyone eager to see stunning images and learn more about fascinating creatures and species!!! 🦑🪼🦈
