How many types of snakes constrict their prey?

There are three main types of snakes that constrict their prey: boas, pythons, and some species of colubrids. These snakes use their powerful bodies to wrap around their prey and apply pressure, ultimately suffocating it. This method of hunting is effective for capturing larger prey that may be difficult to overpower. Constriction is a key adaptation that allows these snakes to thrive in various environments.
