If convergent evolution tells us anything, its that there are only a certain number of variations that work for a lifeform.
Fins are always best for swimming through water. 5 digits on a hand are always best for picking up and manipulating objects. 2 or 4 legs are best for motion. And certain social structures are best for getting individuals to work together.
Even if they don't operate like us, they probably will be similar to other social structures on earth like ants or bees.
