tarsus

This force relies on the parasite’s highly adapted feet, called tarsi, which are equipped with toothed claws.

The daily health checks involve measurements of the birds' weight, wing length, head-bill and part of the foot called the tarsus.

Additionally, they were smaller and had a slower-growing lower leg bone called the tarsus.

“Furthermore, each leg of mine has seven sections—the coxa, the trochanter, the femur, the patella, the tibia, the metatarsus, and the tarsus.”

In addition, it hosts the smallest primate in the world, the tarsus tarsier, which fits in the palm of your hand.
