Final answer:
The scientific name of raccoon roundworms is Baylisascaris procyonis, a parasitic organism classified within the phylum Nematoda.
Step-by-step explanation:
The scientific name of raccoon roundworms is Baylisascaris procyonis. These organisms belong to the phylum Nematoda, commonly referred to as nematodes or roundworms. Nematodes have a wide variety of species, some of which are free-living, while others, like B. procyonis, are parasitic, potentially affecting human health if transmitted.
The diversity of nematodes can be appreciated when considering that the phylum includes over 28,000 known species and some scientists believe the actual number could exceed one million. They have a characteristic round, non-segmented body, a pseudocoelom, and a complete digestive system which contrasts with flatworms. The cuticle-covered body and hydrostatic skeleton of roundworms make them one of the most adaptive and abundant creatures, found across various habitats.
