In any event, he says he admires the work, because he knows how tough it is to study these snakes in particular. Maybe the flying snakes are just sort of at one end of the continuum.” “If we look at their close relatives, can we actually see some precedents for the behavior. “Really, how special is this ability in flying snakes?” says Jayne. Large trees have an even more significant substructure: primary roots that are perennial and secondary roots that grow in waves as the canopy is expanding. If either one of these missions fails, the tree is much more likely to die.
( Read about a venomous snake species discovered in Australia.) The growth of tree roots is all about the search for nutrients and the support of the tree’s canopy. Is jumping “an escape behavior? Is it a common transport behavior? Is it just something they do for lulz? Nobody knows, right?”īruce Jayne, a functional morphologist at the University of Cincinnati in Ohio, says Graham’s decision to study the close relatives of flying snakes is smart, because it could give us a better idea of how these jumping and gliding behaviors evolved. “To be the first person studying this behavior means you don’t really know the context in which a snake does it,” says Graham. Found in India, southern China, and Southeast Asia, king cobras are the only snakes in the world to build nests for their eggs. They can also move forward while looking a 6-foot-tall (1.8-meter-tall) person in the eye, a third of their body raised up off the ground. King cobras avoid humans, but when cornered they can deliver enough venom in their bite to kill 20 people. The first tree snake Graham caught happened to be a rather large female, who was “not interested in doing this jumping behavior at all.” Of course, getting the wild animals to perform those behaviors on the jungle gym was no easy task. ( Read how scales are key to snake locomotion.) “What’s interesting about these snakes is their ability to do all these interesting locomotive behaviors with no limbs,” says Graham. But all of those behaviors require fancy appendages that snakes lack. And sloths simply reach out and grab the next limb they want to travel to. By and large, when you take a step forward, you can count on the ground being there to receive your foot.īut for animals living in the treetops, the world is a highly disconnected affair. Most of us take the fact that we live on a two-dimensional plane for granted. “It’s basically a little snake jungle gym,” says Graham.īy investigating how snakes move around their environment, the scientists have revealed more insights into the diversity of animal locomotion, which has implications for how these bizarre behaviors may have evolved.
Eager to learn more, Graham traveled to Australia, where she temporarily captured some Dendrelaphis animals from the wild and coaxed them into performing their behaviors in a lab experiment, on a structure made out of PVC pipe, tree branches, and GoPro cameras.
