Why do ostriches have 4 kneecaps?
“The upper kneecap actually seems to decrease the leverage of the knee muscles, not increase them,” says Regnault. This sounds like a disadvantage, but it seems to allow the ostrich to straighten its leg more quickly at the knee, albeit at the cost of needing more force to do so.

Why can an ostrich not fly?
Ostriches, emus, cassowaries, rheas, and kiwis can't fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can't possibly lift their heavy bodies off the ground.

Currently voted the best answer.

What are elephant toes?
And although their feet may look like tree trunks, inside the anatomy is more complex. Their five conventional toes point forwards, giving elephants a tip-toed stance, but the extra "toe" points backwards into the heel pad, adding extra support and helping the heaviest land animal to hold up its bulk.
What is a group of emus called?
