What is the difference between the class Adenophorea and Secernentea?
Most Adenophorea are non-parasitic. Free-living nematodes generally feed on bacteria, fungi, and protozoans. Secernentea are almost all parasitic and primarily terrestrial. Their hosts include plants, invertebrates, and vertebrates.
What are the classes of nematodes?
The two primary classes in phylum Nematoda are Enoplea and Chromadorea. Both classes consist of free-living and parasitic worms that live in a wide variety of habitats. They are distinguished from each other through anatomical features.
What are Enoplea characteristics?
Description. The Enoplea are distinguished from the Chromadorea by a number of characteristics. The enoplean esophagus is cylindrical or “bottle-shaped”, compared to the bulbous chromadorean esophagus. Enopleans have pocket-like amphids, while chromadoreans have amphids shaped like slits, pores, coils, or spirals.
What are the three classes of nematodes?
Subclasses of Enoplea Nematodes
- Enoplia – They have oval or pouch-like amphids, cylindrical oesophagus, and smooth bodies.
- Dorylaimida – The majority of this species is a free-living organism. They can be predators or omnivores. Some, like Trichinella, exist as parasites.
- Class Chromadorea.
How many species of Enoplea are there?

What does the Enoplea eat?
Enoplida – marine and brackish water, feed on diatoms, algae etc.
Which is also known as Class Phasmidia?
1. class Phasmidia – one of two subgroups of Nematoda used in some classification systems. Phasmidia. Aschelminthes, Nematoda, phylum Aschelminthes, phylum Nematoda – unsegmented worms: roundworms; threadworms; eelworms.
What are general characteristics of nematodes?
Nematodes are bilaterally symmetrical, elongate, and usually tapered at both ends. Some species possess a pseudocoel, a fluid-filled body cavity between the digestive tract and the body wall. Like arthropods and members of six other phyla, nematodes secrete an external cuticle that is periodically molted.
How many classes are in Nematoda?
two classes
The phylum Nematoda is divided into two classes: Adenophorea and Secernentea.
