Great apes are a group of primates that include orangutans, gorillas, chimpanzees, and bonobos. They are known for their larger size compared to other primates and their advanced cognitive abilities. Great apes are characterized by their lack of tails, strong social structures, and the ability to use tools. These animals are primarily found in tropical forests and savannas of Africa and Asia. Great apes are closely related to humans, sharing a significant percentage of their DNA. They are considered endangered due to habitat loss, poaching, and the illegal pet trade, making conservation efforts crucial for their survival.
