One medium-size whale carcass delivers as much food to the dark, cold ocean depths as 4,000 years of sinking food particles. When a dead whale arrives, the café opens for business. Hagfish, zombie worms, sleeper sharks-this group of patrons is stranger than the denizens of the Mos Eisley Cantina in Star Wars. In this nonfiction picture book, a fish in a lab coat, piloting a deep-sea submersible, serves as guide to the weirdly fascinating goings-on miles beneath the ocean surface. The backmatter includes actual deep-sea whale-fall photos from the Monterey Bay Aquarium Research Institute and other sources
