What are the types of hyphal traps?

Hyphal traps are specialized structures formed by certain fungi to capture and immobilize prey, particularly protozoa and nematodes. The main types of hyphal traps include 1) adhesive hyphae, which secrete sticky substances to ensnare prey, 2) constricting rings, which tighten around the prey when they make contact, and 3) spiral traps, which are coiled structures that can ensnare and hold prey. These adaptations enhance the fungi's ability to obtain nutrients from their environment.
