Ostriches have two kneecaps (patellae) per knee, a unique anatomical feature not found in most other animals

They possess a "true" patella (similar to humans) and a smaller, additional patella that's closely attached to the lower leg bone

The second kneecap might allow ostriches to straighten their knees more quickly, potentially contributing to their high speed

Ostriches are large, powerful, charismatic birds with numerous claims to fame and are the largest living member of the avian family

They are the fastest animals on two legs and are the only animals to bear twice the regulation number of kneecaps

Ostriches have long necks, muscular legs, and claw-like feet, and their bodies are covered in large, fluffy feathers

Some researchers suggest that the second kneecap helps protect the tendons that run across the front of the knee

While these theories provide potential explanations, the exact function of the second patella in ostriches remains a subject of ongoing research
