Final answer:
Spiders are known for creating webs that act as pitfall traps for capturing their prey, a behavior that exemplifies their predatory adaptation.
Step-by-step explanation:
The animal that makes a pitfall trap to catch its prey is a spider. Spiders are well-known for creating intricate webs, which serve as traps for catching insects and other small prey. This behavior is a remarkable example of animal adaptation and predatory tactics. One of their key survival skills is the production of silk, which is used to craft these webs. The spider's ability to trap prey without direct pursuit allows it to conserve energy and capture prey efficiently. Once an insect becomes ensnared, the spider can immobilize it with venom before consumption.
