The Peruvian spider monkey (Ateles chamek) also known as the Black-faced black spider monkey, is a species of spider monkey that lives not only in Peru, but also in Brazil and Bolivia. At two feet (0.6 m) long, they are relatively large among species of monkey, and their strong, prehensile tails can be up to three feet (1 m) long. Unlike many species of monkey, they have only a vestigial thumb, an adaptation which enables them to travel using brachiation. Peruvian spider monkeys live in groups of 20-30 individuals, but these groups are rarely all together simultaneously. The size and dynamics of the resulting subgroups vary with food availability and sociobehavioral activity. They prefer to eat fleshy fruit, but will change their diet in response to scarcity of ripe fruit. Individuals of this species also eat small animals, insects and leaves based on availability. Females separate from the band to give birth, typically in the fall. These females inhabit a group of core areas where resources are abundant in certain seasons. Typically, males exhibit ranging over longer distances than females, with movement of individuals enhancing the fluidity of subgroup size. Peruvian spider monkey are independent at about 10 months, with a lifespan of about 20 years.
The Peruvian spider monkey weighs up to 20 pounds (9 kg.). Its body can be 24 inches (0.7 m) long and the tail can be 36 inches (1 m)long. It has four elongated fingers and virtually no thumb, which is typical for spider monkeys but unusual for other monkeys. It can move easily through the trees and it uses its tail like an extra limb in a type of locomotion known as brachiation. It has an agility that can only be compared to the gibbon of Asia. It has a life span of up to 20 years.
Allen's swamp monkey (Allenopithecus nigroviridis) is a primate species categorized in its own genus Allenopithecus in the Old World monkey family. Systematically, it is a sister clade to the guenons, but differs in dentition and habits.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
