As photosynthetic organisms, seaweeds and other algae transfer billions of tons of carbon globally from the atmosphere to the deep ocean each year. Coming in all manner of colors, shapes, and sizes, from bioluminescent single-celled algae to giant kelps, they form the basis of most marine food webs, and are found in almost all environments on the planet. Touted as the biofuel of the future, seaweeds and algae also hold promise for biodegradable packaging, offer a nutritious food source, and exhibit antiviral and antitumor properties. Combining accessible text with stunning images and graphics, this book takes a deep dive to explore the unique characteristics of seaweeds and other algae, outlining their extraordinary evolution as well as their morphology, life histories, ecology, and uses. Offering rare insights into the algal world, The Lives of Seaweeds is essential reading for naturalists and marine life enthusiasts.
