Etymology and origins
A different (standing) pose is given the name Ushtrasana in the 19th century Sritattvanidhi. The modern pose is described in the 20th century by two of Krishnamacharya's pupils, Pattabhi Jois in his Ashtanga Vinyasa Yoga, and B. K. S. Iyengar in his 1966 Light on Yoga.
Ustrasana is a deep backward bend from a kneeling position; the completed pose has the hands on the heels. The backs of the feet may be flat on the floor, or the toes may be tucked under for a slightly less strong backbend.
The name Ardha Ustrasana, Half Camel pose, is given to two different poses. One is an easier modification with the hands on the hips; the other has one hand on the heel on the same side, as in the full pose, and the other arm stretched back over the head.
