The waters that surround Australia and New Zealand are full of weird and wonderful fish. Jellyfish that impart stings from the uncomfortable to the lethal; tuna with the head of a dolphin; fish that fly. This book investigates these and many other unusual marine stories in a series of articles by Australian marine biologist Julian Pepperell. Fish Might Fly also answers intriguing questions as: Are fish colour blind? How can you tell the sex of a fish? Can fish learn to avoid hooks? Do marlin change sex?
