The Yucatan black howler^[1], also called the Guatemalan black howler or Central American black howler, is a New-World monkey native to Central America.

• Dense, rich black fur drapes the entire body of the Yucatan Black Howler monkey, except for a bald spot on the underside of the prehensile tail.
• Everything about them looks elongated, from full faces to skinny fingers. Their tiny eyes are almond-shaped and brown in color, and they have a protruding snout.
• Males have an enlarged hyoid bone located in the anterior midline of the neck between the thyroid cartilage and the chin.
• It may look like they have swallowed a small oval serving plate, which has gotten hopelessly stuck in their throat.
• Like other members of the Atelidae genus, A. pigra has a prehensile tail with prehensile pads.

• The Yucatan black howler monkey is the largest species of howler monkey and among the largest monkeys in the New-World.
• The Yucatan black howler monkey is known as a “baboon” in Belize. However, it’s not really a baboon.
• The Central American Black Howler nourishes on many plant matters including Pumpwood (Cecropia peltata).
• A typical group of Yucatan black howler monkeys comprises a dominant alpha male, some females, their young, and occasionally additional males, probably involved in defending the group from predators.
• They often live in close association with spider monkeys.
• According to the Guinness Book of World Records, howler monkeys are the loudest land animals.
