Dear Marine Mammal Community, We are seeking marine mammal images for the 3rd edition of *Marine Mammals of the World: A Comprehensive Guide to Their Identification*. Authors Tom Jefferson, Bob Pitman, and I, along with illustrator Uko Gorter, are planning to launch the book at the SMM Biennial Conference in Perth, Australia, in 2024. We are looking for a wide variety of outstanding photographs of common and rare species to expand our coverage. In addition to showing important field characteristics, we also want images of unusually marked and colored animals, known or suspected hybrids, and characteristic and interesting behaviors. For this new edition, we also want to include drone and aerial still images of as many species as possible. For rare or extralimital species, we will also accept images of stranded or beached animals. Image submission is open until August 2023 and should consist of low-resolution files preferably linked to Google Drive or Dropbox, etc., or sent as attachments (up to 20 mb) in an email to me at MarcwebberMMotW3@gmail.com. Include relevant data (date, location, any interesting details). Images selected will need to be sent as high-resolution files. Every photographer whose image appears in the book will receive a free electronic copy of the book, along with a discount code to purchase a hard copy from the publisher at a 30% discount. Thanks to all of you who contribute – it's through the generosity and talent of our colleagues that this book has become, we believe, the best available guide to marine mammals. Please contact me with any questions. Marc Webber Research Associate The Marine Mammal Center
