The Owl Monkey (Aotus spp.) as an Animal Research Model-Part 1: Taxonomy, Geographic Distribution, Anatomy, and...

Area of Science:

• Primate research
• Animal models
• Nocturnal simian primates

Background:

• Owl monkeys (Aotus spp.) are the sole nocturnal simian primates, differing significantly from diurnal nonhuman primates.
• Despite 50+ years of use in malaria research, their captive requirements are poorly documented compared to other primate models.
• Their nocturnal nature complicates in-situ study, limiting understanding of natural behaviors and environmental needs.

Purpose of the Study:

• To provide a comprehensive overview of owl monkey biology and behavior.
• To aid researchers and animal care personnel in optimizing captive husbandry for Aotus spp.
• To enhance the utility of owl monkeys as a biomedical research model.

Main Methods:

• Review of existing literature on owl monkey taxonomy.
• Compilation of data on geographic distribution.
• Synthesis of information on anatomical and behavioral characteristics.

Main Results:

• Detailed summary of owl monkey taxonomy and global distribution.
• Description of key anatomical features relevant to captivity.
• Overview of natural behaviors influencing captive care requirements.

Conclusions:

• Understanding owl monkey natural history is crucial for effective captive management.
• This review serves as a foundational resource for researchers and caretakers.
• Improved husbandry can enhance the welfare and research potential of Aotus spp.
