Enterobius vermicularis is a small, white, nematode parasitic helminth that infects humans, particularly children. It is commonly known as the pinworm. The following are its general characteristics:

Respiration: Enterobius vermicularis does not have lungs or specialized respiratory structures as it obtains oxygen through its body surface.

Reproduction: Female worms lay thousands of eggs per day in the anal area, which causes severe itching. The eggs are then transmitted to other hosts through direct or indirect contact.

Size range: Adult females of Enterobius vermicularis measure about 8-13 mm long and 0.4-0.7 mm wide, while adult males measure about 2.5-5 mm long and 0.1-0.2 mm wide. The eggs typically measure about 50-60 μm by 20-30 μm.
