“That long neck gives the Siebenrock’s snake-necked turtle (Chelodina siebenrocki) a huge advantage.” – JoelSartore, #NatGeoExplorer and founder of the #PhotoArk “It recoils and shoots forward like an arrow from a bow to snap up prey in an instant. They lay in wait and when something swims by, they can nab prey quickly. Why risk having a neck you can't pull into a shell unless the payoff is huge? But that super-capability comes with a catch. Like so many aquatic species, they’re deeply vulnerable to drought, pollution and sedimentation. They need clean water to survive…just like us.” – This species was documented by Sartore at the Tennessee Aquarium. Photo Ark uses the power of photography to inspire people to learn about the captivating lives and remarkable behaviors of weird and wonderful wildlife — and to take action to safeguard them from growing threats.
