To better understand the question we should know that a phylum is a term used to describe a certain group of organisms within various kingdoms, based on many biological traits. Phylums account for a vast number of organisms, that although often similar, each have their own traits.
The phylum Nematoda is the option most likely to confuse readers. This is not the correct answer because members of this phylum are not segmented worms. The question states that the observed worm is segmented, so it is not of the Nematoda phylum.
The phylum Arthropoda is famous for possessing exoskeletons. This is a trait that is very noticeable and easy to spot, the lack of mention of an exoskeleton tells us that the worm in question does not belong to the Arthropoda phylum.
The Platyhelminthes phylum consists of flat-bodied worms which are unsegmented. This alone allows us to conclude that the worm in question does not belong to this phylum.
The Annelid phylum classifies a vast number of worms. Worms in this group are known to:
- Be segmented
- Have appendages
- Be brightly colored
With this information we can conclude that the brightly colored, segmented worm with bristly appendages described belongs to the Annelida phylum.
