Why a field biologist made these

I’m a field biologist, and I drew these sea creatures from animals I’ve actually studied. Free printables are everywhere — but most copy clip art and skip the science. I made these because I wanted true-to-life ocean animals on the page and real facts beside them.

Every fact is checked. A narwhal’s “tusk” is really a tooth — an inside-out canine packed with nerve endings. That accuracy is the point — and it’s why these beat a random free printable.

Made by a working biologist

I still spend my days in the field — along the coast, on the water, and tracking life beneath the waves. These pages grew out of that work, and buying them supports it. No fake reviews here — just honest artwork and a real love of the ocean.
