Marine biologist Angela Ziltener from land-locked Switzerland has been the only one studying the Indo-Pacific bottle-nose dolphins of the Egyptian Red Sea for over a decade. She knows almost all of the 350 individual animals here individually and "her" dolphins became world famous when they starred in Blue Planet II. At the same time, the animals are under severe threat from fisheries, pollution and unregulated tourism which severely interferes with their behavior. Now - as the corona pandemic has decimated tourism on Egypt's Red Sea coast - the dolphins are making a comeback on the reefs. Angela is witness to a real change in the dolphins which are now more relaxed and relatively stress free. Ultimately, this could have a positive effect on their reproductive success, potentially leading to a dolphin corona baby boom next year. The current crisis not only provides a unique window of opportunity for Angela's research but also offers an opportunity to rethink dolphin tourism in Egypt and re-design it in a more sustainable form when tourism eventually does bounce back.
