How Animals Breathe

“When edi­tor Mar­i­lyn Salomon called to offer me this project, I ini­tial­ly said no. The dead­line was tight, and I had just fin­ished a huge project and want­ed to take a break.

So I delved into the research, learn­ing about the book lungs of spi­ders, the spir­a­cles of insects, the gills of fish and oth­er water crea­tures, and of course our lungs. I learned that some frogs take in up to half of their air through their skin and a few tur­tles can breathe through their butts! Aren’t ani­mals amazing!”
