The illustrations are largely in shades of brown and yellow, due to the subject matter, and placed on pages that are often solid pastels, which showcase the spiders nicely.

The spiders are done in a fashion that is realistic, but a tiny bit cartoonish, which might help readers who are a bit squeamish about the real thing.
I'm a big fan of sharing STEM read alouds with the very youngest children in order to get them interested in all facets of science and technology. This is an excellent collection of poems to use along with Animal Ark: Celebrating our Wild World in Poetry and Pictures, National Geographic Book of Animal Poetry: 200 Poems with Photographs That Squeak, Soar, and Roar!, and Lizards, Frogs, and Polliwogs by Douglas Florian
