Authored by Julian Pepperell, leading Australian marine biologist and world authority on oceanic fishes, Fishes of the Open Ocean is the first book to describe and detail the biology and complex world in which these fish live. This unique guide provides information on all major species- billfish, tuna, and pelagic sharks and rays- as well as insights into many lesser known ones, including flying fish, lancetfish, giant sunfish, and the enigmatic oarfish. Divers, anglers, mariners and anyone with an interest in the ocean will find this book an essential reference.
