NuDi Gill: Poison Powerhouse of the Sea

Meet Gill, a flashy nudibranch (noo-de-brank) living a fierce and fascinating life in the ocean without a shell and completely… NAKED!

When a curious young snorkeler stumbles upon Gill, she learns there is more than meets the eye when it comes to her sassy new friend. This soft-bodied mollusk is anything but vulnerable, turning a diet of dangerous ocean creatures into a poisonous sting of its own.

Found in unique shapes and colors in every ocean throughout the world, Gill and his diverse family of nudibranchs serve as a reminder that being small doesn’t mean you can’t have it all!

Published by Gnome Road Publishing.

Sea Smiles

When an otherwise harmless apple becomes the instrument for losing a tooth, a young girl is ready to retire her smile. That is… until she discovers teeth can give us all a lot to smile about.

This humorous, informative story is sure to be a hit with any kid who has lost a tooth, is about to, or just loves learning cool and fascinating facts about animals with weird teeth in the sea! Take a look inside the mouth of a Wolffish, penguin, sea krait and more. Then count up those teeth, and prepare to be surprised. One of these smiley sea animals has over 750,000 “teeth” – and it won’t be the one you’re expecting!

Author-illustrator Bonnie Kelso brings blasts of color, texture and fun to an adorable cast of characters who make the business of losing teeth entertaining, and yet a normal part of life. It’s a perfect addition to any library, home, or dental office waiting room.

Author Visits

I love to visit schools, libraries and museums!

My picture book, Nudi Gill, is an informational fiction picture book for children ages 5 – 8 that explores themes of ocean recreation, wildlife and environmental stewardship.

The first fiction picture book dedicated to nudibranchs, Nudi Gill is fun, informative and entertaining. As an author illustrator and teaching artist, my programs engage children with creative projects. This is a hands-on presentation that sparks the imagination while introducing children to a fascinating marine species.
