Roundworms are indeed visible to the naked eye, making them distinct from some other common parasites. These elongated, often cylindrical worms can range in size from a few inches to even over a foot long, depending on the species. Their size and the fact that they can be found in feces or vomit often lead to easy identification by pet owners and veterinary professionals alike.

In comparison, whipworms and hookworms are much smaller and typically require a microscope for identification, as they are less than two inches in length and are often found in the intestines of the host. Coccidia, a type of single-celled parasite, are also microscopic and not visible without the aid of a microscope. This highlights the unique nature of roundworms, making them an important parasite to recognize during veterinary assessments.
