This volume explores the diversity of distributed eyes and other unusual visual systems in nature. It compares the unique themes of optics, neural processing, and behavioral control that emerge from these visual systems with more-canonical eyes. This volume attempts to answer a number of questions about distributed visual systems. What are distributed visual systems good for, how do they function, and why have they arisen independently in so many phyla? Why are eye designs and visual system arrangements much more diverse in invertebrates? Each chapter includes an overview of the visual systems that exist in their group of animals, relates vision to ecology, and takes a comparative approach.

Box jellyfish are responsible for about 20 to 40 deaths in the Philippines each year. The sting of one species of box jellyfish can kill a person in 3 minutes! While these are some of the deadliest jellyfish, all species of jellyfish sting, both for defense and to hunt for food. Full-color photographs introduce readers to the growing population of jellyfish in Earth’s oceans. From the strange-but-cool life cycle of the jellyfish to the specifics of their stinging tentacles, the main text includes interesting science content, astonishing fact boxes, and safety information about sharing the oceans with these stinging creatures.

This flexible resource combines character education with analogies to powerful stories from nature. The heart of each of the book’s twenty-five lessons is an engaging story, written to kids, describing a particular animal or plant and its distinctive qualities. Busy classroom teachers will like this book’s accessibility and flexibility. Kids can read a story individually or in groups, or follow along as the teacher reads it aloud. Accompanying each story, teachers will find several activities—most of them quick, easy, and requiring few supplies—that further investigate animals or plants and the connections between their qualities and human behaviors. Every lesson examines several main character traits, providing starting points and sample questions for discussing and exploring analogies between events in nature and human acts of character. Features include a chart cross-referencing lessons to specific character traits and a list of further resources. Digital content contains all of the book’s reproducible forms, including a color photo of each plant and animal, plus a complete bonus lesson.

Examines some of the more unusual or dangerous creatures that inhabit the ocean, including the great white shark, orca, and giant tube worms.
