Seadragon is instant messaging for humans and cetaceans (whales and dolphins). “It allows you to emit whistles underwater and to see the text names of whistles emitted by cetaceans in response to yours.” While the application attaches names to received clicks and whistles, it’s up to you to interpret their meaning. “This Version 1.0 Beta is for early adapters: adventurous cetacean communication scientists or whale watchers with a technical bent.”
