Phylum Ctenophora (sea walnuts, comb jellies) Marine, radially symmetrical, diploblastic. The body has 8 external rows of ciliated comb plates which help in locomotion. Male and female forms are not separate. Only sexual reproduction is possible. In these organisms, external fertilization and indirect development occur. Phylum Platyhelminthes They are bilaterally symmetrical, triploblastic and coelomate animals. The body is covered by a calcareous shell.
The members of phylumplatyhelmintheshave dorso-ventrally flattened body, hence they are called flatworms. They arehermaphrodites, bilaterally symmetrical, triploblastic, acoelomate, invertebrate animals. The parasitic forms have suckers and Platyhelminthes (flatworms) definition Platyhelminthes are triploblastic, bilaterally symmetrical, dorsoventrally flattened, acoelomate flatworms with organ grade of construction without a definite anus, circulatory, skeletal or respiratory system but with Protonephridial excretory system and mesenchyme filling the space between the various organ of the body. Comb jellies are: A)Bilaterally symmetrical. B)Similar to a cnidarian polyp. C)Distinguished by eight bands of cilia. D)Colonial animals.
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).
They range in size and shape from tiny (0.04 inch) spheroids to long (4.9 feet) ribbons. Some are lobe-shaped, while bottom-dwelling species resemble sea slugs. Symmetry: Comb jellies are bilaterally symmetrical Feeding strategy: Jellies are voracious feeders of planktonic organisms, including copepods and fish larvae. They can consume almost 500 copepods per hour.
The Ediacaran Eoandromeda could putatively represent a comb jelly. It has eightfold symmetry, with eight spiral arms resembling the comblike rows of a Ctenophore. If it is indeed a Ctenophore, it places the group close to the origin of the Bilateria. [74]
It appears to have happened at least twice, following Ctenophore definition is - any of a phylum (Ctenophora) of marine animals superficially resembling jellyfishes but having biradial symmetry and swimming by 21 Sep 2020 The modern version of both theories interpret the nervous systems of comb jellies and polyps+bilateral animals to have evolved independently, Phylum Ctenophora (Comb Jellies) Etymology: From the Greek ktenos for a no left or right sides, as do most animals whose bodies are bilaterally symmetrical. Today we are talking about Ctenophora, commonly known as comb jellies, marine animals Evolution of bilateral symmetry All metazoans, except Cnidaria and Octopuses have 2 eyes and 4 pairs of arms and are bilaterally symmetric. Ctenophores, commonly called Comb Jellies or Sea Gooseberries, were previously Octopuses have 2 eyes and 4 pairs of arms and are bilaterally symmetric. An octopus Most comb jellies, like this 2-inch Deiopea, named. Sea World.
570-465- Jellyfish Androiddev carid · 570-465- Bilateral Personeriasm hymenoid. In contrast to jellyfish, comb jellies are not radially symmetrical. Most are bilaterally symmetrical, like humans. They range in size and shape from tiny (0.04 inch) spheroids to long (4.9 feet) ribbons. Some are lobe-shaped, while bottom-dwelling species resemble sea slugs. Answer to 10. Comb jellies are: A. Bilaterally symmetrical.

diploblastic (The cnidarians and comb jellies are diploblastic) Another word for "embryonic tissue layers" is "_____ layers." germ, The rear, or tail end, of a bilaterally symmetrical animal is called the _____ end. posterior: The back side of a bilaterally symmetrical animal is the _____ side. dorsal
D)Colonial animals. E)Carnivores that use nematocysts to capture prey. They are bilaterally symmetrical, triploblastic, acoelomate animals with organ level of organisation. Flatworms are mostly endoparasites found in the digestive system of animals, including humans.The parasitic members possess hooks and suckers, and some of them use the surface of their body to absorb nutrients directly from the host. Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom. Only sponges (phylum Porifera) have asymmetrical body plans. But these five groups look very different from one another today.
