Difference between Roundworm and Hookworm

Roundworm

Roundworms belong to the phylum Nematoda. Most of them are parasitic in nature. They inhabit a diverse range of environments. They are slender worms that are typically 0.1 to 2.5 mm in length. Their epidermis is covered by a collagenous cuticle. Below the epidermis is a layer of muscle cells. Their unique feature is the presence of a tubular digestive system. They also have openings at both ends.

The parasitic roundworms comprise the ascarids, hookworms, pinworms, filarias and whipworms. The majority of them reside in the top layer of the soil.

Hookworm

They are a type of blood-feeding, parasitic, intestinal roundworms. The two notable species of hookworms are Nectar americanus and Ancylostoma duodenale. The former can only infect by penetrating the skin, while the latter can also infect through oral routes. Most of them have a hooked appearance, and they get attached to the wall of the intestine.
