Shapeshifters: The Wondrous World of Jellyfish is a breathtaking collection of photographs and expert commentary that shed light on the most mysterious creatures of the deep sea.Jellyfish come in a dazzling array of colors, shapes, and sizes, drifting through every ocean, from the surface to the deepest of the deep seas, and are even found in freshwater locations. These ancient creatures, also called sea jellies (they are not, technically, fish), are so otherworldly and luminous that it is no wonder they are often compared to mythical shapeshifters. Some are so delicate that they shatter with the smallest disturbance to the water, while the tenacity of others means they can withstand almost any temperature, any salinity, starvation, and even being dismembered. And some are truly biologically immortal.This visually breathtaking book showcases 100 species of jellyfish within its pages--from the ubiquitous Aurelia to the enigmatic Velella--along with astounding facts about these fascinating marine life-forms. Some are splendid, some strange, some poisonous, some deadly. Some carry surprising secrets, and some are barely known, but every one of them is remarkable and has a tale to tell. An introduction by noted expert Lisa-ann Gershwin, with her commentary throughout, invites you into the wondrous world of jellyfish.
