Follow one of the ocean's most mysterious animals in this warm but candid look at its dramatic life cycle, from the creators of The Nest That Wren Built. These are the shells she wears like a sheath, keeping her safe from Tiger Shark's teeth when she's far from the den that Octopus built . The solitary and ingenious octopus is a master of disguise and invention, creating her den out of the objects of the ocean, from shells and rocks to tiny glass shards. Using creative methods of hunting and construction, the octopus prepares for the biggest task of her life: motherhood. With one last, poignant gesture of love, the mother octopus sends her hatchlings on their way, starting a new cycle of life for the tiny offspring who face peril of their own. Offering deeply informative back matter, including an author's note, a glossary, and fascinating "octo-knowledge" (did you know that octopuses have nine brains, including one in each of their independently operating arms?), this third in a series from author Randi Sonenshine and illustrator Anne Hunter continues the work of gently introducing children to the reality of the animal world.
