assistant
The main difference between a saguaro cactus and a prickly pear cactus is their size. A saguaro cactus can grow up to 50 feet tall, while a prickly pear cactus typically grows much smaller, around 6-12 feet in height. Saguaros also have thicker trunks than prickly pears, which are often hollow inside. Prickly pears also tend to be more spherical in shape than saguaros, which are usually more cylindrical.
