Boa constrictors are generally lighter in color than pythons with a series of ovals separated by dark-colored, saddle-shaped patches.  The dark saddles usually have a light spot on each side, and the light ovals tend to become darker and often reddish colored toward the tail. The head is shaped similar to a Burmese python's, but boas have a thin, dark wedge on the head rather than a broad arrowhead. Boa constrictors typically reach 8-10 feet in length, although a few grow up to 13 feet.

There is considerable color and pattern variation in boa constrictors. The red-tailed variety is popular in the pet trade.
