Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose. The legs are stocky and the ears and tail are small. However, the feet are very large to distribute load when walking on snow or thin ice and to provide propulsion when swimming; they may measure 30 cm (12 in) across in an adult. The pads of the paws are covered with small, soft papillae (dermal bumps), which provide traction on the ice. The polar bear's claws are short and stocky compared to those of the brown bear, perhaps to serve the former's need to grip heavy prey and ice.The claws are deeply scooped on the underside to assist in digging in the ice of the natural habitat.
Now you see me... now you don't! This #trapdoorspider burrow appeared to be vacated on the cheetah exhibit this morning. Perhaps it left due to the heat and succumbed to a bird beak as a tasty morsel... but that's just a possibility...
