Boop! Up close with Cuba, a Dall sheep. Behind this gentle, curious face is a species built for extreme, rugged alpine ranges. This male Dall sheep (Ovis dalli) named Cuba was documented by #NatGeoExplorer JoelSartore at the Plzen Zoo and Botanical Garden in Plzen, Czech Republic. The National Geographic Photo Ark uses the power of photography to inspire people to delve into the captivating lives and remarkable behaviors of wildlife and explore solutions to safeguard them from growing threats.
