Zombie Fish

Tapeworms aren't just a problem for people. They control a fish called the stickleback, directing it to superhot water where the tapeworm has a chance to grow as big as it can. If the tapeworm gets its way--and it often does--infected fish end up with huge bellies full of a tapeworm that may be bigger than the fish! Readers learn all about this terrible parasite as well as others that turn fish into zombies. Full-color photographs enhance intriguing science content, including how the fish survives a parasitic infestation and how each parasite spreads.
