Indonesia's tropical reefs are the richest in the world, and North Sulawesi - a volcanic region ringed with coral and swept by fertile currents - is renowned for the diversity and beauty of its marine life. This volume captures the vivid colours and bizarre forms of Sulawesi's underwater realm in some superb photographs. Some of them are extraordinary, including a baby cuttlefish bursting from its egg or a blue-ringed octopus snatching a crab, while others present rare creatures new to science, such as a glowing orange mantis shrimp.
