2025-08-18 00:00:00 Welcome to the “eSeaAnimals” app of Aquatic Animal Virtopsy Lab (AAVL) from the City University of Hong Kong! Reporting the occurrence of aquatic animals in our ocean is important for science and conservation. Your quick reporting may help save an animal’s life by providing rescuers with real-time information about the location and kind of aquatic animals in trouble and allowing scientists to collect valuable information that will help aquatic animal conservation. The app allows you to share your sightings of cetaceans (whales, dolphins, and porpoises) and sea turtles with scientists whenever you are at sea, fishing, diving, sailing, swimming or just enjoying the beach time. By collecting information from sightings of cetaceans and sea turtles, we can significantly improve their research and protection, as this makes it easier to identify areas of the presence of individual species, trends in their abundance, and especially the occurrence of rare and new species.
