Introduction
Intraguild predation is a very widespread and important interaction in many systems. It happens when two or more species that make use of similar resources, making them competitors, also also have predator-prey interactions. In the Coachella Valley, California, four scorpion species engage in intraguild predation among themselves. Polis & McCormick (1987) carried out a study on these four scorpion species, and concluded that the most abudant scorpion limited the growth of the others, not through competition, but rather via predation.
