This is a lovely book for children at the age when they first start doing research papers. It's told as a 'biography,' and has no notes except for a brief thanks to experts, but it certainly would work as a supplementary source. And it works as pleasure and family reading, with lovely illustrations. There is some predator/prey action, and some circle-of-life reality, but nothing more than any child needs to learn, and since it takes place underwater, the gore isn't visible. I recommend it.
It’s always nice to read about these surprisingly intelligent and sensitive animals as they really are, rather than as cartoonish comic foils or sushi ingredients.
This book profiles the complex life of an adult female octopus as she looks for food, avoids predators, finds a mate, and lays and guards her eggs.
