Vivid illustrations by Aaron John Gregory pair with engaging, carefully researched stories that connect behavior, habitat, and surprising natural history details. The book invites readers to look beyond familiar seaside sights and discover the rhythms, strategies, and quirks of mollusks—snails, squids, clams, and slugs—revealing how these animals spend their hours.","[OceanofPDF.com](OceanofPDF.com)  \nPraise for Shell Day  \n“Do you ever ask yourself, What do mollusks do all day? Or perhaps even, What is a mollusk? You’ll find the answers here. You’re sure to learn something, as I did, while you enjoy this informative book that highlights members of the second-most diverse but often-overlooked animal phylum, which includes snails, squids, clams, and slugs. Though still animals, those creatures are about as distantly related to you and me as possible. They offer a different and fascinating take on life.” Janet Voight, author of From the Seashore to the Seafloor  \n“Marine biologist Helen Scales introduces readers to twenty-four remarkable species of mollusks, each revealing fascinating behaviors that unfold over the course of a typical molluscan day. Beautifully illustrated and packed with engaging and informative stories, this book offers delightful insights into the lives of those extraordinary animals.” Andreia Salvador, senior curator of marine Mollusca at the Natural History Museum, London  \nPraise for Scales  \n“With the soul of a poet and a talent for finding the most intriguing trivia about familiar seaside sights, marine biologist Scales turns the mundane into the magical.” Discover  \n“A sprawling, ambitious underwater journey studded with fascinating tidbits.” New York Times Book Review  \n“Punctures assumptions with the power of a cone snail dart.” Spectator  \n“An enchanting, accessible tour of the seashell and its place and purpose within the natural world.” Kirkus Reviews  \n“Scales . . . brings a marine biologist’s eye and aficionado’s heart to these musings on seashells. . . . [Her] eclectic approach to this ancient bridge between the human and natural worlds conveys her curiosity and appreciation.” Publishers Weekly  \n“A fascinating journey into the strange and captivating world of mollusks. Carefully researched and entertaining throughout. . . .
