Ctenophores, commonly known as the Comb Jellies have biradial symmetry. Regarding the number of germ layers, Ctenophores are a little controversial. Traditionally, these animals are considered to be diploblastic. But nowadays according to many, they are recognized as triploblastic animals with a mesenchymal middle layer.

Comb jellies are: A)Bilaterally symmetrical. B)Similar to a cnidarian polyp. C)Distinguished by eight bands of cilia. D)Colonial animals. E)Carnivores that use

They have eight external rows of ciliated comb plates, which help in locomotion. Pleurobrachia and Ctenoplana are some common ctenophores. Ctenophores, commonly known as Sea Walnuts or comb jellies. They are exclusively marine, radially symmetrical, diploblastic organisms with tissue level of organization. The body bears eight external rows of ciliated comb plates, which help in locomotion. Digestion is both extracellular and intracellular. Jellyfish and corals are example of radially symmetrical.

Comb jellies are bilaterally symmetrical

These animals are marine, radially symmetrical, diploblastic with tissue level of organisation. Reproduction is sexual. Eight rows of ciliated comb plates support the body. This is why they are commonly known as comb jellies or sea walnuts. Scope of Biology.

They are commonly called flatworms and live inside other organisms.

Ctenophores are commonly known as sea walnuts or comb jellies. These animals are marine, radially symmetrical, diploblastic with tissue level of organisation. They have eight external rows of ciliated comb plates, which help in locomotion. Pleurobrachia and Ctenoplana are some common ctenophores.

Most are bilaterally symmetrical, like humans. Young jellyfish are small enough to be part of the general zooplankton The bands divide the body into eight symmetrical parts.

9 Jul 2020 Which one of the following groups of animals is bilaterally symmetrical and triploblastic ? play. 60040147. 900. 19.3 K. 3:33. Comb jellies

Comb jellies are bilaterally symmetrical

• Body bears eight ciliated comb plates which help in locomotion. • Bio-luminescence (to emit light) is present in Ctenophores. • Hermaphrodite, fertilization external, development indirect, Radially Symmetrical Animals With Tissues: Phyla Cnidaria and Ctenophora Note: the radially symmetrical Cnidarians and comb jellies. They usually have no definite head and are often sessile. Bilaterally symmetrical animals are symmetrical along a plane dividing the body into right and left halves. Radiata.

Typically found under rocks, sea floor or attached to other organisms.

In these organisms, external fertilization and indirect development occur. Phylum Platyhelminthes There are sponges, comb jellies, cnidarians (including sea anenomes, corals and jellyfish), bilaterally symmetrical animals (such as humans and clams) and obscure, microscopic worms called placozoans. Comb jellies ctenophora Sponges porifera Features Asymmetrical or Radial from BIOS 3300 at Ohio University, Athens The two halves of a radially symmetrical animal may be described as the side with a mouth (“oral side”) and the side without a mouth (“aboral side”). This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies). Ctenophores, commonly known as sea walnuts or comb jellies are exclusively marine, radially symmetrical, diploblastic organisms with tissue level of organisation.

Male and female forms are not separate. Only sexual reproduction is possible. In these organisms, external fertilization and indirect development occur. Phylum Platyhelminthes There are sponges, comb jellies, cnidarians (including sea anenomes, corals and jellyfish), bilaterally symmetrical animals (such as humans and clams) and obscure, microscopic worms called placozoans.

4. PHYLUM PLATYHELMINTHES Flatworms Are Acoelomate (no Body Cavity) And Have Bilateral Symmetry. Some Are Parasitic While Others This

The body bears eight external rows of ciliated comb plates which help in, locomotion (Figure 4.8).

Comb jellies have long given evolutionary biologists difficulties. They are uncertain how the sponges, the jellyfish and corals (the cnidarians), the comb jellies, and the bilaterally symmetrical

Orthosymmetric Ucakambulans excide.
