Sea without a shore Life in the Sargasso

Five major currents in the Atlantic Ocean "swirl billions of gallons of water clockwise around and around," creating an immense body of water, called the Sargasso Sea after the floating sargassum forests within it. Though it's known as seaweed, Rosenstock (Mornings with Monet) explains in clear, punchy prose that sargassum is an algae that reproduces when small pieces break off and then photosynthesize, growing stipes and blades as "gas-filled globes keep the weed on the surface." In carefully drafted naturalistic watercolors, Roy (The Fire of Stars) paints the sargassum floating in the blue sea as sunlight streams down, then focuses on the tiny creatures that settle upon it, in turn supporting more sophisticated life-forms: "Pinching Crabs,/ Skittering Shrimp." These beings tidy the weed, which keeps "floating,/ around and around," a phrase whose repetition reinforces the sea's sense of movement. As the title indicates, seas don't need seashores to be distinct, nor do thriving ecosystems require land. Around a series of ever larger creatures depicted--fish, turtles, and whales, all sustained by sargassum-supported life--are images of people of various skin tones interacting with the algae. Ample back matter concludes. Ages 4--8. (Sept.)

From the broken-off tip of a sargassum plant, a whole community grows in the Sargasso Sea. This appealing title illustrates the remarkable variety of "the ocean's floating golden rainforest," as marine biologist and oceanographer Sylvia Earle puts it in her afterword. Set on and off the shores of Bermuda, the book depicts racially diverse beachgoers making their own whirlpool as Rosenstock describes the enormous whirling area of the Atlantic Ocean known as the Sargasso Sea, the result of "five currents [swirling] billions of gallons of water clockwise." Next, she introduces the sargassum, an algae that reproduces by growing anew from broken-off bits. Step by step, the sargassum grows, and other living creatures--crabs, shrimp, swordfish--come. They graze on it, take shelter in it, and feed on smaller inhabitants. Gradually, the population builds up until we see humpback whales and then a happy Black-presenting human swimmer. The author makes clear how interdependent these creatures are and describes the complexity of their world. This deftly told narrative would be grand fun to read aloud. The creatures are introduced in triplet lines: "Crusty bryozoans / feathery hydroids. / Spiraled tube worms." Rosenstock's concise text exudes energy and makes wonderful use of alliteration: "They scavenge. Snatching and shredding." "Water-striders speed on the surface." Roy's gorgeous, watercolorlike illustrations swirl with vibrant hues and would show well to a group. Youngsters will be sucked into this engaging, informative account of a most unusual ecosystem.
