Gasteracantha kuhli, commonly known as the spiny orb-weaver, is a species of spider found in tropical and subtropical regions. It is characterized by its distinctive spiky abdomen, which is covered in sharp, pointed spines. These spines serve as a defense mechanism against predators and also aid in camouflage. Gasteracantha kuhli constructs intricate orb-shaped webs to catch prey, primarily insects.
