Are nematodes mollusks?

Nematodes are not so obviously related to annelids and molluscs, either in the structure of the animals themselves or in the form of their embryos.

What do nematodes and molluscs have in common?

What do insects, nematodes and molluscs have in common? They are invertebrates because they don't have backbones. What do reptiles, birds and mammals have in common? They have lungs, they reproduce by internal fertilisation rather than external fertilisation.

What is the difference between annelids and nematodes?

Nematodes have an unsegmented body whereas annelids are metamerically segmented. Nematodes are pseudocoelomate, whereas annelids have a true coelom. Nematodes are dioecious, i.e. sexes are separate. Annelids are mostly hermaphrodites and free-living.

What family are nematodes?

Nematodes in the Tylenchidae family are one of the most important soil-inhabiting species, yet little is known about this intriguing group.

Is a nematode an annelid?

The key difference between nematodes and annelids is that nematodes are roundworms which are not segmented while annelids are true segmented worms. ... Both nematodes and annelids are invertebrates with elongated bodies, and they prominently feature among worms.

Do nematodes have complete digestive system?

Unlike the flatworms in which food and waste enter and exit from the same opening, nematodes have a complete digestive system. An animal with a complete digestive system has a mouth at one end, a long tube with specialized parts in the middle, and an anus at the other end.

In which habitats do molluscs live?

Habitat and Locomotion

Most mollusks are marine animals; some are found in shallow coastal areas and others live in the deepest parts of the ocean. Most live in the bottom sediments, though the cephalopods are primarily free-swimming species.

What is the difference between platyhelminthes and nematoda?

The main difference between Platyhelminthes and Nematoda is that Platyhelminthes consists of flatworms with a thin, dorso-ventrally flattened body whereas Nematoda consists of a cylindrical body, which is tapered to fine ends at each end. Tapeworms, Turbellaria, Trematoda, and Monogenea examples of Platyhelminthes.

Do Nematodes have appendages?

Nematodes are pseudocoelomate members of the clade Ecdysozoa. They have a complete digestive system and a pseudocoelomic body cavity. ... They are characterized by a segmented body and jointed appendages. In the basic body plan, a pair of appendages is present per body segment.

Do nematode and annelid body plans differ?

How do nematode and annelid body plans differ? Nematodes lack body segments and a true coelom; annelids have both.

How can you tell the difference between an annelid and a nematode quizlet?

a. Nematodes have a muscular pharynx, with no muscles in the intestine ( gut ), and they have a longitudinal muscles in the body wall. ... Annelids have a circular and longitudinal muscles in the body wall and a digestive system.

Are nematodes microorganisms?

Among the microorganisms found in the soil are bacteria, actinomycetes, fungi, micro-algae, protozoa, nematodes, and other invertebrates (mostly arthropods).

Are all nematodes the same?

There are many many species of nematode in the natural world but they are all target specific. We sell nematodes for specific garden pests and they do not affect anything else. By applying nematodes to you are garden you are boosting a population that is already there without upsetting the delicate ecosystem.

Are nematodes arthropods?

Nematodes are in the same phylogenetic grouping as the arthropods because of the presence of an external cuticle that protects the animal and keeps it from drying out. There are an estimated 28,000 species of nematodes, with approximately 16,000 of them being parasitic.
