The phylum Nematoda is divided into two classes, Adenophorea and Secernentea. The main basis for this subdivision is the absence (Adenophorea) or presence (Secernentea) of the phasmid sensory organ described in the Roundworms: Characteristics (Advanced) concept. Most Adenophorea are non-parasitic.
What is the life cycle of nematodes?
The life cycle of nematodes consists of six stages or instars: the egg (or embryo), four juvenile stages (Jl, J2, J3, J4) and the adult (Figure 6.1). All nematodes possess this basic pattern. The immature stages have been called ‘juveniles’ by plant nematologists and ‘larvae’ by animal helminthologists.

Answer: The Aschelminthes (also known as Aeschelminthes “Nemathelminthes” “Nematodes”), closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right.
