Ambush predator
Ambush predators or sit-and-wait predators are carnivorous animals or other organisms, such as some nematophagous fungi and carnivorous plants, that capture or trap prey by stealth or by strategy (typically not conscious strategy), rather than by speed or by strength. In animals, ambush predation is characterized by an animal scanning the environment from a concealed position and then rapidly executing a surprise attack.
