How dolphins say I love you with a bouquet of seaweed: They’re also pushy parents, make best friends for life – and exfoliate every day

This is a great article and most of it is true to what we have seen.
I am not sure of the romantic explanation of the seaweed, since they have played that game, also with leaves, and other sea grass with Don, my self and other swimmers more as a game. Yet it is noteworthy that Dolphins play these games of trowing a leaf so to speak in order for it to be caught by the other, something I have not seen amongst other wild animals.
