Marxxs(VWM136) was born on January 4, 2009 in the Whiskers Mob. His mother was the dominant female, Ella, and his father was the dominant male, Thundercat. Marxxs' litter consisted entirely of males. His siblings were Mimaji(VWM138), VWM137 and Pitio(VWM139). All four pups survived their first weeks and foraged with the the group. The "M" in Marxxs' ID code was changed to an "F" indicating that he was believed to be a female. This was later confirmed a mistake and was changed back. In April 2009, VWM137 disappeared and was assumed predated. The rest of the litter survived to adulthood. The remaining brothers began roving, with Pitio roving the most. In February, 2011, Marxx was attacked by his father and evicted from the group. He returned a few days later. He soon became one of the oldest
