Why don’t snakes have armpits?

Introduction: The Curious Case of Snake Anatomy

Snakes are fascinating creatures that have intrigued humans for centuries. Their unique anatomy and behavior have been the subject of many studies and research over the years. One of the most interesting aspects of snake anatomy is the absence of armpits. This raises the question: why don’t snakes have armpits?

Understanding Armpits: Their Function and Importance

Armpits, also known as axillae, are the hollow spaces under the arms where the arm bones meet the shoulder blades. They are lined with sweat glands, hair follicles, and lymph nodes. Armpits play an important role in regulating body temperature by producing sweat, which cools the body as it evaporates. They also act as a filter for lymphatic fluid, which helps fight infection and disease. Additionally, armpits are a source of pheromones, chemical signals that play a role in social and reproductive behavior in many mammals.
