Ocean Secrets of the deep

A dive into the ocean's wonders, from edge to abyss.De Amicis' painted illustrations give this wide-angled survey a strong visual draw, as sea life floats on every page in grand displays of exotic shapes, gracefully angled fins and spikes, tendrils and tentacles, intricate patterns of dots and stripes. We really have just one ocean on this planet, Weiss points out, and we know less about it than we know about the moon or Marsso she begins by pairing mermaids with manatees, the legendary kraken with the real giant squid, before going on to profile characteristic residents of each oceanic zone from sunlit surface to the dark and eerie world at the bottom of the deepest trenches. She then surveys local habitats from polar seas to salt marshes, glides past diverse topics from symbiosis and other relationships to sea creatures that change sexes, and, after glances at climate change, "plastic soup," and other threats, closes with a set of basic principles of environmental care. Each marine creature on view is identified and accurately depicted, with occasional small silhouettes of humans or other animals to provide a sense of relative scale.It's broader that it is deep, but it offers both a global view and art to pore over.
