Knowra New World monkey New World monkey New World monkeys are platyrrhine primates native to Central and South America. They are distinguished from Old World monkeys by broad, outward-facing nostrils and several skeletal and dental traits.
Platyrrhini : The primate parvorder comprising all New World monkeys. This taxonomic name identifies the group and its defining anatomical lineage.
Arboreal locomotion : Movement through trees by climbing, leaping, or suspending from branches. Many species navigate forest canopies through specialized climbing and leaping.
South American primate fossil record : The fossil evidence documenting primate evolution and diversity in South America. Fossils reveal extinct forms and help date the group's diversification on the continent.
Callitrichidae : A family of small New World monkeys that includes marmosets and tamarins. These small-bodied monkeys have distinctive claw-like nails and cooperative infant care.
Tropical deforestation : The clearing or degradation of forests in tropical regions. Forest conversion fragments the habitats on which many species depend.
Anthropoid : A primate group comprising monkeys, apes, and humans. New World monkeys belong to the broader anthropoid radiation.
Seed dispersal : The movement of seeds away from parent plants by animals, wind, water, or other means. Fruit-eating monkeys deposit seeds far from parent plants, shaping forest regeneration.
Caviomorpha : A group of South American rodents that includes capybaras, guinea pigs, and chinchillas. Rodents and platyrrhines are thought to have reached South America in separate dispersal events.
Atelidae : A family of New World monkeys including howler, spider, woolly, and woolly spider monkeys. Its members include the largest New World monkeys and the strongest examples of prehensile tails.
Habitat fragmentation : The division of continuous habitat into smaller, isolated patches. Fragmentation restricts movement and can isolate monkey populations in forest remnants.
