Thank you.
Ok, eusocial, this is a term we give to animals that have attained the highest level of social order, on par with or surpassing humans (a lot of controversy as to whether we are eusocial or semi-social.) As of 1966 eusociality can be defined with these four characteristics:
Animals cooperate effectively and care for their young
Animal generations interlock, this means that a mother might live at the same times as her son and so might the grandmother...generally because they look after each other and there is less worry about predators. Also children always outnumber the amount of predators.
Different animals are given different jobs, sometimes this even develops into a strong caste system much as in a human society.
There is a strong relation between eusocial and colonial animals such as bees, wasps and insects, one should also note that there is a difference between eusocial, the highest order and then sub-social and pre-social which are lower levels.
Funnily enough Darwin noted with a little apprehension that he could not at first explain eusociality and how it worked with his theory of evolution because these creatures generally have a mostly sterile colony and therefore their genes barely get passed on. A lot of creationists swarmed on this (if you'll pardon the pun) and still do but it isn't really an argument against evolution now because there are proofs, notably selective or inclusive fitness. Anyway I digress.
Now, a super queen is really a term coined by myself in this thread and I suppose I should say that super queens and queens are the same thing. I suppose you might want to know how a queen forms in the animal world? Well I could tell you what the
current theory for how a queen bee forms but I would suggest that we look more intrepidly at termite queens because they are more akin to the queen sligs/mudokons/glukkons (for reasons I won't bother the argument with unless you ask specifically). Now, there are usually multiple queens in a termite colony in the same generation, this means that rather than being mongamous, genetic information is more varied and widely spread which is good for increasing the radiation of a selected species. A termite queen molts, through that big word ecdysis, therefore when the new 'shell' grows on the abdomen is more distended than before, this also means another set of ovaries can grow increasing maximum efficiency of reproduction.

Note the enormous abdomen in this prime queen, similar to Sam, she is practically immobile and is surveyed by an honour guard of termites to help her around and take her eggs away.
So in conclusion, eusociality is and order of sociality whereas a queen is the status given to a matriarch for a colonial species.
The next question has been partially explained in the first but I will continue, the queen (super queen) must have the acquired traits to have such an extended abdomen, in termites ecdysis is used to slowly grow the abdomen and therefore, provides more room for a queen to hold sperm and her ovaries. A bird does not have an abdomen like a insect queen and eusocial mammals do not have a queen but rather a matriarch.
If we were being hypothetical and said mudokon birds were at some point eusocial, they would probably have a matriarch like an elephant of wolf, a mother that reproduces for the colony. But somehow, as the mudokon evolved, the female that wasn't sterile acquired an enormous distended abdomen.
I hope that helped.
