Least concern. Least Concern Extinct. Current Population Trend: Decreasing. Share Tweet Email. Go Further. Animals Wild Cities This wild African cat has adapted to life in a big city. If the monkeys are monogamous, the baby monkey may be cared for by both parents.
Many times, a young monkey will ride on its mother's back or hang from her neck. The baby is considered an adult between four and five years old. The taxonomy of a monkey depends on what type of money it is. The higher categories are the same for all monkeys:. After order, the classifications become specific to the type of monkey. Here are some example classifications for two types of monkeys. While many monkey species are not in danger, there are some that are very close to extinction.
For example there are only Tonkin Snub-Nosed monkeys in existence. Another monkey on the list is the Tana River Red Colobus. There are fewer than 1, of these monkeys left in the world. The Hainan Black-Crested Gibbon is considered one of the most critically endangered species. There are only 20 of these monkeys left in the world. If there is a lack of food, female monkeys will stop mating until there are better circumstances for getting pregnant.
Even when conditions are right, a mother will only give birth once every two years. They substitute other fruits and leaves when figs are scare. Daily time spent foraging for and consuming figs increases with increased abundance of the food source. Like Ateles paniscus and several other species of Ateles , Ateles chamek are large and are not easy prey for other similarly sized species.
Despite the size of Ateles chamek , larger members of the family Felidae , such as jaguars, Panthera onca , do consume black-faced black spider monkeys. Symington, In addition to natural predators, humans tend to be the largest threat for black-faced black spider monkeys. Humans in the surrounding areas hunt and consume black-faced black spider monkeys as food. Also, expansion of the agricultural industry and logging in Peru, Bolivia, and Brazil has increased the rate of habitat degradation.
Replacement of the natural forests with agriculturally valued crops decreases the abundance of potential food sources for Ateles chamek. This process also creates larger open areas, making black-faced black spider monkeys an easier target for hunters. Wallace, et al. Little is known about if or how Ateles chamek warn other social group members of potential predators. Black-faced black spider monkeys disperse seeds of the plants that are common in black-faced black spider monkey diets.
Although they tend to favor figs, they consume over species of fruits, often ingesting the seeds and then dispersing them through defecation. The majority of the seeds eaten by black-faced black spider monkeys remain intact throughout this process.
Seed distribution also occurs when they carry food for some distance before ingesting the fruits. Black-faced black spider monkeys provide a source of meat for hunters in areas surrounding the monkey populations. Because of the significant decrease in the population of Ateles chamek in recent years, several measures have been taken to limit the amount of hunting of this species of spider monkey. There are no known adverse effects of Ateles chamek on humans. The additional human threats of hunting and deforestation make it even more likely that the number of Ateles chamek will continue to decline over time.
Limitations or bans on hunting black-faced black spider monkeys in their natural habitat may improve the status of this species, but it may be unlikely that this effort will be substantial enough to help the species recover completely.
In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.
Convergent in birds. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes.
