anatomy. The pseudocoelomates include the nematodes, rotifers, gastrotrichs, and introverts. Some members of some other phyla are also, strictly speaking, pseudocoelomate. These four phyla of tiny body size (many species no larger than the bigger protozoans) are placed together in part because they…
: an invertebrate (such as a nematode or rotifer) having a body cavity that is a pseudocoel.
Beside this, Which of the following is an example of Pseudocoelomate?
An example of a Pseudocoelomate is the roundworm. Pseudocoelomate animals are also referred to as Blastocoelomate. Acoelomate animals, like flatworms, have no body cavity at all. Semi-solid mesodermal tissues between the gut and body wall hold their organs in place.
Likewise, What phylum has Pseudocoelom?
The pseudocoelomate phyla are Gastrotricha, Rotifera, Nematoda, Nematomorpha, Kinorhyncha, Loricifera, Acanthocephala.
Also, Is tapeworm a Pseudocoelomate?
Coelomates and Pseudocoelomates Figure 2 illustrates the three basic body plans encountered in the bilateria: the acoelomates (e.g., flatworms, flukes, and tapeworms), the pseudocoelomates (e.g., roundworms, pinworms, hookworms and rotifers), and the coelomates (e.g., snails, clams, octopuses, earthworms, and leeches).
Which of the following is Pseudocoelomate?
Hookworm is Ancylostoma, it is an Aschelminthes animal and is pseudocoelomate as their body cavity is Pseudocoelom (fluid filled body cavity present in between the mesoderm and ectoderm). Jellyfish is a Coelenterate animal and is acoelomate. Thus, the correct answer is option C.

Are mollusks Pseudocoelomates?
Terms in this set (19) mollusks are pseudocoelomates. … mollusks have a two-opening one-way digestive tract.
Which are Pseudocoelomates?
A pseudocoelomate is an organism with body cavity that is not derived from the mesoderm, as in a true coelom, or body cavity. A pseudocoelomate is also known as a blastocoelomate, as the body cavity is derived from the blastocoel, or cavity within the embryo.
Are mollusks Pseudocoelomates or Coelomates?
Animals in the phylum Mollusca include clams, snails, octopuses, and sea slugs (pictured right). They are all protostome coelomates. Mollusks are characterized by their soft bodies, which are usually protected by a hard calcium carbonate shell.
Is Earthworm a Pseudocoelomate?
Coelomates and Pseudocoelomates Figure 2 illustrates the three basic body plans encountered in the bilateria: the acoelomates (e.g., flatworms, flukes, and tapeworms), the pseudocoelomates (e.g., roundworms, pinworms, hookworms and rotifers), and the coelomates (e.g., snails, clams, octopuses, earthworms, and leeches).
Where is the Coelom of a mollusk?
Be careful not to tear open the coelom, located near the hinge of the shell. Note how the mantle encloses the visceral mass, and creates a mantle cavity, an open space around the internal organs.
Which worms have a Pseudocoelom?
Roundworms make up the phylum Nematoda. Roundworms have a pseudocoelom and hydrostatic skeleton. Their body is covered with tough cuticle. Free-living roundworms are found mainly in freshwater habitats.
What differentiates Pseudocoelomates from Acoelomates?
Acoelomates and coelomates are two types of triploblastic animals, which differ according to the basic body plan. Most acoelomates and coelomates are invertebrates. Acoelomates do not develop a body cavity or a coelom. In contrast, coelomates develop a fluid-filled coelom from the mesoderm.
What are Pseudocoelom?
The pseudocoelom is a fluid-filled body cavity lying inside the external body wall of the nematode that bathes the internal organs, including the alimentary system and the reproductive system (PeriFIG 1).
Do annelids have Pseudocoelom?
True coelom: The coelom of an annelid is a large space in which the internal organs form. Since the body is segmented, the coelom is segmented, too. This makes annelids different from nematodes, which have a pseudocoelom.
What is Pseudocoelom give example?
An example of a Pseudocoelomate is the roundworm. Pseudocoelomate animals are also referred to as Blastocoelomate. Acoelomate animals, like flatworms, have no body cavity at all. Semi-solid mesodermal tissues between the gut and body wall hold their organs in place.
Are annelids Pseudocoelomate?
Pseudocoelomates: The Phylum Nematoda Annelids, cnidarians, and flatworms also have hydrostatic skeletons. Giant kidney worms are able to parasitize many mammals, including humans. The female worms can grow up to 5 feet long.
Are insects Pseudocoelomate?
Animals such as earthworms, snails, insects, starfish, and vertebrates are all eucoelomates. A third group of triploblasts has a body cavity that is derived partly from mesoderm and partly from endoderm tissue. These animals are called pseudocoelomates. Roundworms are examples of pseudocoelomates.
