Hookworms have a cylindrical, elongated body that is typically 1 to 2 centimeters in length. They possess a distinct anterior end, which is bent or curved, allowing them to attach to the intestinal walls of their hosts using their specialized mouthparts, equipped with teeth or cutting plates. Their body is covered by a tough, flexible cuticle, and they exhibit a simple digestive system with a mouth, pharynx, and intestine, but lack a separate anus, as waste is expelled through the mouth. Additionally, hookworms have a relatively simple nervous system and reproductive system, with females producing numerous eggs that are excreted in the host's feces.
The hookworm was discovered by Aloysius and Patrick Manson in the late 19th century. They identified this parasitic worm as the cause of anemia in their patients in Asia and Africa.
An internal body-support structure is called a skeleton. It provides support, protection, and structure for the body.
structure means body like the body of the forest

The body structure also known as the cranium is commonly referred to as the skull. It is the bony structure that encloses and protects the brain.
hookworms have bilateral symmetry
No, hookworms do not have a backbone. They are parasitic roundworms belonging to the phylum Nematoda, which means they are invertebrates. Unlike vertebrates, which have a backbone made of vertebrae, hookworms have a simple, elongated, cylindrical body structure.

Is a hookworm radial
Hookworm is endoparasites. From: Micol Colico :)
The doctor administered a hookworm prevention shot.
Itching also may be caused when any of the family of hookworm larvae penetrate the skin. This includes swimmer's itch and creeping eruption caused by cat or dog hookworm, and ground itch caused by the "true" hookworm.
Yes, a hookworm is a parasite that sucks blood via the tissue of an intestine it infects.

It has bi-lateral symmetry, although it's so simple a creature you could almost argue for radial symmetry.
well what i found is that a hookworm can live 2 weeks without food.
