Nice post about the intelligence of some organisms!
It is super intersting the different ways of communication that organisms have to have survival. Funnily enough, there are plenty of ways they can achieve it by communicating it to different parts or organisms of the society.
My favourite example you put was the one of the bees. Strong pheromones after a bite & dancing patterns for the rest of the hive to communicate? It is weird. It makes you wonder about the nature of "information" as such. For them means food, or attack. For us, means nothing. As if they were different languages.
Pretty cool if you ask me! :D
