👉 The aye fluid, also known as polypore gland secretion, is a unique and specialized substance produced by certain species of bats, particularly those in the family Molossidae. This fluid is a clear, viscous liquid found in the grooves of their elongated middle fingers, which they use to probe and extract insects from tree bark or other hard surfaces. The fluid is highly elastic and contains enzymes that help break down the exoskeletons of their prey, making it easier for the bats to capture and consume them. Additionally, the fluid may serve other purposes, such as lubricating the bat's fingers or providing some form of sensory feedback during foraging. This remarkable adaptation is a fascinating example of evolutionary specialization in bats, enhancing their ability to thrive as nocturnal insectivores.
