They are also known to build difficult to make toys (air bubble vortex rings) to entertain themselves.
They have to discover how to make it. Sometimes they can be quite possessive, they would break the toy if someone not so knowledgeable wants to play with it. Once a dolphin figures it out how to make one, his/her peers eventually figure it out too. So it kind of spreads within a group like fashion. This behavior has been observed both in captivity and in the wild.
They also have what appears to be fratricide were they bludgeon another to death targeting vital organs (I dont have a reference to this, but I recall reading it on BBC).
I have seen dumber people on and around TV.
I am sure there are HN'ers who are divers and have first had experience with dolphins, we would love to hear the stories.
