flatworms are the only triploblastic organisms that lack a coelom
Flatworms, such as tapeworms and planarians, are examples of acoelomate animals. These animals lack a true body cavity called a coelom and have a solid body structure instead.
No. A coelenterate is an animal (such as a jellyfish), whose main body cavity is also its alimentary canal (gut). Most animals, on the other hand, have a body cavity (called a coelom) that is separate from the gut. For instance, inside your own body, you have an alimentary canal (your esophagus, stomach and intestines) and a separate body cavity that contains your heart, lungs, liver, etc. In a coelenterate, there is only one cavity.
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
Flatworms are in the Platyhelminthesphylum.
Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.
No, a flatworm does not have a body coelom.

Acoelomate is an animal that lacks a body cavity or a coleom.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
Flatworms are triploblastic organisms, meaning they have three germ layers (ectoderm, mesoderm, endoderm) that give rise to different tissues in their body. This allows them to have specialized structures like muscles and nerves. They have a solid body shape, lacking a body cavity or coelom.
Body cavity or coelom is generally the third most important criteria, after levels of organisation and body symmetry, in the classification of animals. Animals can be classified into four types on the basis of the type of body cavity they possess:Acoelomate (coelom absent): includes animals like sponges, coelenterates and flatworms,Pseudocoelomate (false coelom present): includes roundworms, andEucoelomate (true coelom present): includes all chordates, besides rest of the invertibrates.
Platyhelminthes, commonly known as flatworms, are soft-bodied invertebrates with a flattened body shape. They exhibit bilateral symmetry and lack a coelom (body cavity). They are hermaphroditic, meaning they have both male and female reproductive organs.
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
It was appeared in nematodes.Annelides had first true coelom.
