17 Major Difference between Roundworm and Tapeworm with Table

What is the difference between roundworm and tapeworm?

Parasites normally invest in the intestines of cats, dogs, and human beings. Roundworms, tapeworms, and hookworms are common examples of parasites.

The core difference between roundworm and tapeworm is that roundworm has a cylindrical body tapered shape while tapeworm is a dorso-ventrally flattened tape-like body shape.

Difference between Roundworm and Tapeworm

What Is Roundworm?

Roundworms are parasitic worms found in the intestines of mammals. There are about 80,000 species of roundworms in the world.

These parasites are also known as nematodes and they have a cylindrical body shape. They have cuticles that prevent the body from expansion and produce fluid pressure in the pseudocoelom.

These parasites have a complete digestive system. It has a head marked with bristle sensory and solid shields. Some nematodes are hermaphrodites and others are dioecious.

What Is Tapeworm?

Tapeworms are long ribbon-like parasitic flatworms that are found inside the intestines of mammals. There are about 500 species of tapeworm in the world.

The scolex which is the head of the tapeworm contains tentacles for sucking liquids. These parasites have an incomplete digestive system.
