animals that live closely together and have a dominant leader.

clickInsocial animals, thealphais the individual in the community
whom the others follow. Where one male and one female fulfil this
role, they are referred to as the alpha pair (the term varies when
several individuals of the same gender fulfil this role). Other
animals in the same social group may exhibit deference or other
symbolic signs of respect particular to their species towards the
alpha.In most species, the alpha is given preference to be the
first to eat and the first to mate. Other animals in the community
are usually killed or ousted if they violate this rule. This leads
to the alpha males and females being overrepresented in some groups
in the genetics of a population, because they may become the only
ones who breed successfully.& Wikipedia
