Das Meer steckt voller Überraschungen! Wussten Sie schon … • Dass Quallen zu den ältesten tierischen Lebensformen der Erde gehören – und schon seit 500 Millionen Jahren durch die Meere schweben? • Dass das, was wir sehen , oftmals gar keine einzelnes Lebewesen ist, sondern eine ganze Kolonie vieler Kleinst-Quallen? • Dass Quallen keineswegs beißen, sondern nesseln – und dabei den Schaft der Nesselzelle harpunengleich mit bis zu 40.000-facher Erdbeschleunigung in die Haut des Angreifers schießen? • Dass einige Quallen kleiner als ein Sandkorn sind, andere länger als ein Blauwal? • Dass sie sich klonen können, als Zwitter überleben oder gar unsterblich sind? Mit unzähligen atemberaubenden Fotografien bringt dieses Buch den Bau, die Taxonomie, das Verhalten, die Ökologie und die Lebenszyklen dieser unglaublichen Kreaturen näher und stellt steckbriefartig 50 der bedeutendsten und faszinierendsten Arten vor: Von der winzigen unsterblichen Qualle Turritopsis bis zur riesigen Nomura-Qualle.

Focusing on the captivating nature of jellyfish, this guide presents an in-depth exploration of 50 species, highlighting their unique anatomy, life histories, taxonomy, and ecological roles. With stunning photographs accompanying each profile, readers are invited to discover the resilience and beauty of these ancient creatures, which have thrived for over 500 million years. As jellyfish populations continue to grow in response to environmental changes, understanding their fascinating stories becomes increasingly important.

Our oceans are becoming increasingly inhospitable to life-growing toxicity and rising temperatures coupled with overfishing have led many marine species to the brink of collapse. This book tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations.

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.
