From the Look Closer series, this richly illustrated concertina book takes you on a journey through the deep dark waters, all the way down to the seabed, before floating back up to the surface. A follow-up to The Street Beneath My Feet, The Skies Above My Eyes and The World Around Me, this visually stunning book ventures to the very bottom of the sea on a journey of discovery. Through the waves and into the deep, you’ll spot all kinds of weird and wonderful marine creatures, explore the seabed and discover the impact humans have had on the underwater world.  As you dive below the surface, past sea otters playing in fields of giant kelp, you will see sea lions and shoals of mackerel playing in the shallows, before passing orcas hunting in pods in the deeper water. As well as animals, discover the technology which is used under the sea, from scuba breathing apparatus to oil pipelines and deep sea submarines. As you reach the very bottom of the sea, the 'twilight zone' where very little light can filter through, you will meet the mysterious creatures of the deep such as Lanternfish and the luminous swell shark. This book is part of the Look Closer series, a set of concertina books which help teach us about the mysteries which can be found in the world around us.
