Male dolphins summon buddies to help them attract and defend females in heat by learning the signature whistles of their allies and remembering who cooperated with them in the past. This concept of team members has previously been seen only in humans, and such teams can last for decades. Each dolphin learns a unique signature whistle from its mother, which it keeps for life, and they recognize and remember each others' whistles. The study team's high tech approach will help unlock other mysteries of cetacean communication -- such as what female dolphins are saying when they whistle.
