An update in very important whale/dolphin friendship news

You guys! Remember yesterday, when we learned that dolphins and whales in Hawaii have twice been caught spontaneously playing together? Apparently, this gets better. Dolphins in a French aquarium seem to be "speaking" whale—making whale-sounding noises at night that mimic the actual whale noises they hear all day on the soundtrack to the aquarium dolphin show they perform in. These dolphins have never met real whales. But dolphins are known mimics and it seems that they're capable of practicing and improving on mimicked sounds hours after the sound has gone away.
