Is an hookworm bilateral or radial?

It is also known as 'small intestinal roundworms', belonging to the phylum Helminths. All nematodes are shown bilateral symmetry with the head being radially symmetrical, pseudocoelomate. Complete answer: Ascaris, hookworm, and whipworm are parasitic worms referred to as soil-transmitted helminths (STH).

What kind of symmetry do hookworms have?

Nematodes are one of the most common phyla of animals, with over 20,000 different described species. Like other nematodes, hookworms have bodies that are long and slender and taper at both ends. While think and round in cross section, they are actually bilaterally symmetric. Adult females of A.

Are worms radial or bilateral?

Worms are the first significant group of animals with bilateral symmetry, meaning that the right side of their bodies is a mirror of the left. One type of worm is the flatworm. Worms in the phylum Platyhelminthes are called flatworms because they have flattened bodies.

Is a worm radial bilateral or asymmetrical?

Worms belong to the phylum Platyhelminthes, Aschelminthes and Annelida. They are all bilaterally symmetrical. E.g. tapeworm, roundworm, pinworm, hookworm, earthworm, filarial worm, etc. Radial symmetry is found in animals belonging to the phylum Coelenterata and Ctenophora.

Do roundworms have bilateral or radial symmetry?

Roundworms (nematodes) are bilaterally symmetrical, worm-like organisms that are surrounded by a strong, flexible noncellular layer called a cuticle.

Why do roundworms have bilateral symmetry?

Bilaterally symmetric organisms have two halves that are mirror images of each other. This might be hard to imagine in a roundworm, though, because there are no arms, legs, or any other external structures like this to cue you in to the two identical halves.

Is a human radial or bilateral?

The body plans of most animals, including humans, exhibit mirror symmetry, also called bilateral symmetry. They are symmetric about a plane running from head to tail (or toe). Bilateral symmetry is so prevalent in the animal kingdom that many scientists think that it can't be a coincidence.

What group is a worm in?

Both worms and insects are classified under the Kingdom Animalia. The animal kingdom is split into two groups: vertebrate, animals with a backbone, and invertebrate, animals without a backbone. Both worms and insects are invertebrates.

Is Earthworm bilaterally symmetrical?

Earthworm has 'bilateral symmetry'.

Are flat worms radial or bilateral?

The phylum Platyhelminthes, the flatworms, shows bilateral symmetry. In bilateral symmetry, you create two matching halves by drawing a line from the anterior (head) end of the organism to the posterior (tail) end.

Do all worms have radial symmetry?

They are all bilaterally symmetrical. E.g. tapeworm, roundworm, pinworm, hookworm, earthworm, filarial worm, etc. Radial symmetry is found in animals belonging to the phylum Coelenterata and Ctenophora. Echinodermata exhibits radial symmetry in the adult stage and bilateral symmetry in the larval stage.

What is an example of bilateral symmetry?

Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates. The symmetry of an animal generally fits its lifestyle.

What is an example of radial symmetry?

Because of the circular arrangement of their parts, radially symmetrical animals do not have distinct front or back ends. They may have distinct top and bottom sides. Some examples of these animals are jellyfish, sea urchins, corals, and sea anemones. A bicycle wheel also has radial symmetry.

Are hookworms flatworms?

Other disease-causing flatworm parasites include the lung flukes and liver flukes. Roundworms that cause disease include Ascaris, a large intestinal worm that can grow to the size of a pencil, as well as hookworms and whipworms.

Are Cnidaria bilaterally symmetrical?

Comparative analysis provides evidence that bilateral symmetry is a primary character of Cnidaria. All anthozoan taxa are characterized by bilateral symmetry. ... The bilateral symmetry of Cnidaria is thought to be inherited from the common ancestors of both cnidarians and triploblastic bilaterians.

Is Mollusca a bilateral symmetry?

The generalized mollusc is bilaterally symmetrical and has a single, "limpet-like" shell on top. The shell is secreted by a mantle covering the upper surface. The underside consists of a single muscular "foot".
