‘Mummy, Where's My Dorsal Fin?’ follows the adventures of a little Indo-Pacific finless porpoise calf named Aluna and her mother Cheriya, as they explore their beautiful habitat around the Langkawi Archipelago. Described as a story of discovery, learning, and hope in a changing world, the book was also inspired by the natural beauty of Langkawi. We catch up with marine biologist Dr Louisa Ponnampalam, the Chairperson of the MareCet Research Organisation and author of the book, to find out more about the stories that inspired her first children's publication, and how she and other scientists are using writing and the creative arts to spread the message on conservation of the environment.
