assistant
The main difference between a saguaro cactus and a prickly pear cactus is in their appearance. A saguaro cactus has large, spiky spines that are often orange or red in color. Prickly pears have smaller, smoother spines with more of a yellow-brown color. Additionally, saguaro cacti typically grow larger than prickly pears, with some species growing up to 50 feet tall.
