The largest, swiftest, highest-leaping and most migratory fishes on the planet all live in the open ocean. Beautifully adapted to their world, they range from tiny drift fishes and slow plankton-straining whale sharks to high-energy, streamlined predators such as tunas and marlin. The internationally bestselling Fishes of the Open Ocean, from Julian Pepperell, one of Australia's best-known marine biologists and world authority on oceanic fishes, is the first book to describe these fishes and detail their biology and the complex, often fragile world in which they live. This unique guide covers major species such as tunas, marlin, swordfish and sharks, as well as many rarely seen, such as flying fishes, lancetfish, sunfish, pomfrets, opah, louver, fanfish and basking sharks.
