What is a rope used to catch things called?

A rope used to catch things is commonly referred to as a "lasso." Traditionally associated with cowboys, a lasso is a long, looped rope that is thrown to ensnare animals, particularly livestock. It is designed to tighten around the target when pulled, making it effective for capturing and securing. In broader terms, similar ropes may also be called "catch ropes" or "throw ropes" in different contexts.
