Imagine being invited to visit a mysterious place where only a few have ever been; where only they have truly seen the creatures that inhabit it; and where it's murky depths are accessible by only one type of vehicle. Would you dare to go? Lydia Lukidis and Juan Calle extend just such an invitation, but no notes for missing school, packing a suitcase, or plucking of courage need to be considered, for through their phenomenal book, readers find a seat in the incredible submersible that will transport them to "...the deepest underwater valley in the world" the Mariana Trench. The submersible plunges deeper and deeper to where the sun doesn't penetrate. Here, in the darkness, "food is scarce, and a bone-chilling cold blasts through the water. Earthquakes shake the ocean floor, and the water pressure, like a thick, heavy blanket with a thousand hands, presses down, / down, / down." What flashes by the porthole window? A monster? No--a fish with a long and slender tail perfectly suited for its austere home, where it can survive for months without eating if necessary. "Diving deeper, a long, thin body slinks and sways, ever so slowly. The cutthroat eel is not fearsome, some rather, mesmerizing." . . . . Insets of scientific information on diet, anatomical adaptations, and other aspects that make them suited to their environment also accompany the introduction of each sea creature. Back matter includes an illustrated cutaway of the ocean above and descending into the Mariana Trench with various sea creatures labeled and oriented to the level in which they are found; "Did You Know?" facts about the water pressure in the Trench, its creation, and how many people have visited; why the Mariana Trench matters; an author's note; and a glossary. When undertaking an excursion into unknown territory--especially through words and pictures--explorers need guides who can truly immerse them not only in the sights and sounds of an area but also the rhythms and almost intangible aura that makes it so uniquely compelling. Readers of all ages find that quality in Deep, Deep Down. Lydia Lukidis's lithe and lyrical language is at once straightforward--answering questions any reader might have--and evocative--capturing the enigmatic and secret world at the bottom of the Earth as it flashes into view or slowly reveals itself and retreats again. Her vocabulary, rich with active verbs, ensures that readers appreciate the Mariana Trench as teeming with life and alive with wonders more amazing than we can even imagine. Don't be surprised if you find yourself forgetting that you're looking at illustrations of a vampire squid, anglerfish, rattail fish, cutthroat eels, crinoids, and even the rocky and sandy ocean floor instead of photographs as you inspect Juan Calle's magnificent pages. As the submersible--seen from many angles--plunges into darker and darker water, bioluminescent fish begin to appear alongside their grayer sea mates (children will enjoy pointing out the dark shapes that lurk in the shadows of the submersible and the stony outcroppings.) As a rattail drifts into view, each rose-gold scale is visible, shimmering in the beam of light thrown from the submersible; it's blue eye seemingly as curious about readers as they are about this unusual fish. Calle mesmerizes with careful details, shading, and perspective that portrays each creature in all of their weird and wonderful floating, creeping, or stock-still spectacle. Deep, Deep Down: The Secret Underwater Poetry of the Mariana Trench will thrill ocean and nature lovers and will spur increased interest and research into this unique, nearly untouched habitat that we are only now beginning to discover. The book is a must for any environmental science enthusiast at home and for all classroom, school, and public library collections.-- "Celebrate Picture Books"
