For the last 10 years, the Mexican artist Ariel Guzik has searched for a way to communicate with whales and dolphins. Guzik’s project has encompassed the creation of underwater instruments, expeditions to contact whales and dolphins off the coasts of Baja California, Costa Rica and Scotland, and sound recordings of these remarkable encounters. The Holoturian is Guzik's latest underwater resonance instrument, specially designed to communicate with whales and dolphins in the deep seas. It was commissioned by Arts Catalyst and Edinburgh Art Festival and first displayed as an art installation. This book brings together artistic, scientific and environmental reflections on Guzik’s work, the language and culture of cetaceans, and the challenges facing these intelligent creatures in our threatened oceans today. Fully illustrated with texts by curator Nicola Triscott and marine scientist and conservationist Mark Simmonds OBE. Edited by Nicola Triscott Designed by Margherita Huntley
