Roundworms
Roundworms belong to the phylum Nematoda.
Scientific classification: Roundworms make up the phylum Nematoda.
NO Mammals are not arthropods. Arthropods are insects.
Roundworms are a part of the animal kingdom. They are a part of the phylum nematoda. There are several species of roundworms.
There is some debate about what other groups the nematodes, or roundworms, are most closely related to, and therefore from what group they descended. Nematodes are classified as being in the clade Ecdysozoa which also includes arthropods. If nematodes are truly closely related to arthropods then they share a common ancestor.
Roundworms (Nematoda) are related to arthropods because they both molt.Note; Crustaceans are arthropods. :P

Roundworms
The common name for phylum Nematoda is roundworms.
No, arthropods are not radial. They have bilateral symmetry, which means their bodies can be divided into two equal halves. This symmetry is a common feature among many animals, including vertebrates and invertebrates.
Arthropods have segmented bodies, an exoskeleton made from chitin, and joint appendages.

In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
Some common parasitic members of the phyla that infect humans include Platyhelminthes (flatworms) like tapeworms and flukes, Nematoda (roundworms) such as hookworms and pinworms, and Arthropoda (arthropods) like mosquitoes and ticks which transmit diseases.
