What is a characteristic of a longspring or coilspring foothold trap?

A longspring or coilspring foothold trap is characterized by its ability to securely grip an animal's foot when it steps onto the trap. This design features two springs that provide a strong hold, ensuring that the animal cannot easily escape once captured. The effectiveness of this trap lies in its construction, which allows for a reliable capture without inflicting lethal harm immediately. This is especially important for wildlife management, as it enables the safe handling of animals for relocation or further assessment.

Other options mention aspects such as causing serious injuries or being designed for a quick kill, which do not align with the intended purpose of foothold traps. These traps are primarily made for capturing without immediate lethality, preserving the animal for further management actions. Additionally, while some trapping methods may involve water sets, foothold traps are more versatile and can be used in various terrains, not limited to aquatic environments.
