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!

Praise for Nudi Gill: Poison Powerhouse 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. Children will enjoy the brightly colored, digitally generated images, which have an animated feel; a bonus is the (labeled) depiction of other types of marine life, which will allow adult readers to extend the learning by discussing more than the starring nudibranch.”

–Booklist (American Library Association)
