Snow Monkey Hierarchy: the Top Monkeys
The famous Snow Monkeys of Jigokudani are in fact Japanese macaques. This is a highly intelligent species of monkey which lives in large troops of over 100 individuals and is what are considered to be ‘matrilineal’ societies, meaning that a specific monkey’s lineage and status is traced through its mother.
An estimated 60 to 70% of the monkey troop is female, with different family lineages grouped together within one overall ‘dominance hierarchy’. Though mostly female, at the top of this hierarchy sits an ‘alpha male’ – the No.1 monkey and boss of the troop.
Every monkey within the troop is named by park rangers with its lineage accounted for, with specific monkeys holding the highest ranks. These are the top monkey power players in the park:
The Alpha Male: TOAMI 00
Born in 2000, Toami placed the old alpha, Tomamu, in 2019. Through the 1990s, many males were born into the troop and Toami is one of the youngest of that generation. He is aggressive toward the other monkeys and asserts his power through constant confrontations. His distinguishing facial feature is his prominent, protruding forehead. He is young, strong, and looks determined to hold on to his position as alpha for years to come.
Number 2: TOKEI 95-05
The second in line to the throne of the Jigokudani kingdom is Tokei 95-05. Born in 2005 he is notably younger than Toami. Tokei is slightly built with somewhat black fur. Despite his slight and younger appearance, Tokei has a countenance permanently set to threatening. Young and confident, Tokei appears ambitious however hasn’t displayed the drive of Toami to establish himself as the alpha (at least, not yet).
