Conservation Status

Threats

Despite their adaptability, colobus monkeys face significant threats:

• Deforestation: Habitat loss due to agriculture and logging is the primary threat.

• Hunting: In some regions, colobus monkeys are hunted for their striking pelts.

Conservation Efforts

Tanzania has implemented various measures to protect colobus monkeys:

• The creation of national parks and reserves, such as Jozani Forest and Udzungwa Mountains.

• Community-based conservation initiatives in Zanzibar to protect red colobus monkeys.

Fun Facts About Colobus Monkeys

• Colobus monkeys lack thumbs! Their reduced thumb structure allows for better grip while swinging through trees.

• The word “colobus” comes from the Greek word “kolobós,” meaning "docked," referring to their missing thumb.

• Their fur was once highly prized in the fashion industry, leading to significant hunting pressures.
