Nudi Gill

Poison Powerhouse of the Sea

Written & Illustrated by Bonnie Kelso

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!

With illustrations as striking and colorful as Gill himself, this is an underwater adventure like no other where young readers can see for themselves what makes Gill and his fabulous family of nudibranchs tiny, but mighty poison powerhouses of the sea.

      "This is a twofer: a story about a little girl going snorkeling and meeting a new friend, Gill, and a nonfiction overview of the little-covered nudibranch, a brightly colored type of sea slug."
