A fascinating mystery in the natural world is how various forms of life can adhere to vertical or inverted surfaces. A recent report by researchers at Washington State University explains how a salamander’s toes allow it to climb, jump, and glide from limb to limb in the forests from California to British Columbia. The wandering salamander (Aneides vagrans) in this study can control the blood flow to its square-shaped toes.
The toes of these salamanders have blood vessels all the way to the tips. They can control the blood flow in the vessels to expand or contract the surface area of the toes. In this way, these salamanders can attach or detach from tree surfaces. They can release from one limb, glide to another, and instantly attach as they wander through the coastal redwood forests.
Everywhere we look in the natural world, we see that a wonder-working hand has gone before. Many special adaptations in living things enable them to live in challenging environments. God has endowed each living creature with the features necessary to survive and adapt to changing environments. This mechanism in a salamander’s toes could inspire human innovators in the areas of prosthetics and robotics.
