If you are just a tidbit fascinated by jellyfish and companions, buy this book! I have been mesmerized by them for years, but found only kids books. This book is great for both grownups and a bit older kids who can read somehow fluently.
It features many stunning photographs, in addition there are great information about the biology and sociology of these creatures in an easy language.
It's a small book, so if you want to read something heavy and scientic about jellyfishes, this is not for you. If you want a peek into their fascinated looks and lives, this is a gem! It has enough photos to interest a child who cannot read also!
