179.) Tick the false statements. (1) Although radially symmetrical animals are common in the ocean, all land animals are bilaterally symmetrical (2) Choanocytes in sponges trap food by filter feeding and then ingest it (3) Ctenophores, such as comb jellies, move by cilia and have nematocysts to capture their prey (4) Teredo or shipworm is one of the few bivalves that does not filter feed

Ctenophora (/ t ɪ ˈ n ɒ f ər ə /; singular ctenophore, / ˈ t ɛ n ə f ɔːr / or / ˈ t iː n ə f ɔːr /; from Ancient Greek: κτείς, romanized: kteis, lit. 'comb' and φέρω, pherō, 'to carry'; commonly known as comb jellies) comprise a phylum of invertebrate animals that live in marine waters worldwide. 2007-01-29 · Comb jellies are the largest of all animals that utilize the beating of cilia for locomotion. It doesn't stop there - with lengths up to 2 mm, ctenophore cilia are the longest of any known. Each single comb within a row is made up of several thousand cilia, and each row may have dozens of combs, so an individual ctenophore is endowed with many thousands of cilia.

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

The fundamental domain is a half-plane through the axis, and a radial half-line, respectively. Axisymmetric or axisymmetrical are adjectives which refer to an object having cylindrical symmetry, or axisymmetry (i.e. rotational symmetry with respect to a central axis) like a doughnut (torus).

Traditionally, these animals are considered to be diploblastic. But nowadays according to many, they are recognized as triploblastic animals with a mesenchymal middle layer. This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies). Radial symmetry enables these sea creatures, which may be sedentary or only capable of slow movement or floating, to experience the environment equally from all directions.

Answer to 10. Comb jellies are: A. Bilaterally symmetrical. B. Similar to a cnidarian polyp. C. Distinguished bv eight bands of cilia. D. Colonial animals. E.

C)Distinguished by eight bands of cilia. D)Colonial animals. E)Carnivores that use Jellyfish and corals are example of radially symmetrical. When you say radial symmetric, it's a kind of animal that has a surface that have a mouth in the center that can reach out in any direction to be able to catch and eat their foods.  They are bilaterally symmetrical, triploblastic and acoelomates.  They show organ level of organisation.  In parasitic forms, there are organs of adhesion such as hooks, suckersand spines.
