Climbing Salamander: The Amphibian That Scales Trees Using Its Blood-Driven Adhesion
Title: Treetop Trotters: Unraveling Wandering Salamander's Aerial Acrobatics
Hang out with these daring critters: Coastal redwood forests of North America
What they chow down on: Insects, spiders, small arthropods, and snails
The wandering salamander isn't your typical forest dweller. Instead of lurking under logs or wallowing in swamps, this industrious creature thrives high above ground, living life amongst the branches. These arboreal aficionados call the redwood forests home, residing in tree bark crevices and snacking on insects.
Situated over 300 feet (90 meters) above the forest floor, wandering salamanders execute tree-to-tree traversals for resources and foraging. To ensure a secure landing, these agile explorers require a firm grip during descent. A misstep could lead to a tumble to the ground below—not ideal!
So, how do these aerial adventurers maintain a solid grip while navigating the treacherous canopy? The secret lies in their specialized, blood-powered toes. Yes, you hear that right—blood-powered toes!
Similar to how birds use a complex blood system to change the color of their throat feathers, wandering salamanders utilize their arterial and venous networks for a unique gripping mechanism. According to recent studies published in the Journal of Morphology, these specialized appendages play a vital role in the salamander's precise leaping and landing through the forest canopy.
Previously, scientists speculated that the blood flow visible beneath their translucent skinplayed a role in maintaining their feet's oxygen supply. While engaging in high-resolution video trials, biologists led by researcher Christian Brown at Washington State University confirmed that the blood-powered toe tips of the wandering salamander offer an exceptional level of control over their grip on tree bark.
When preparing to jump over branches, the salamander quickly fills the toe tip with blood. The additional blood pressure helps the salamander detach from the tree as the blood influx increases pressure, causing the toe pads to expand momentarily. This slight lift reduces contact area, making it easier to detach from the surface.
However, when landing, the salamanders swiftly drain the blood from their toe tips, softening the toes and increasing surface contact. This allows them to conform better to the tree bark's irregular and rough texture, resulting in a more secure and efficient grip.
The salamander's toe control is dynamic, allowing them to transition between stepping, gripping, or releasing with ease. As Christian Brown herself put it, "If you're climbing a redwood with 18 toes gripping bark, being able to detach efficiently without damaging your toes makes a huge difference."
