ns present in the coelom
Mollusca are in broadened terms coelomates, or animals with a true coelom. This means their gut is suspended by mesenteries in a fluid filled cavity called the coelom. However, cephalopoda, or squids and octopi, are the only mollusks with a closed circulatory system so they are have TRUE coeloms. All the other classes of mollusca are what are known as hemocoels because of their lack of a pericardium and open circulatory. Hemoceols still have true coeloms, they're merely reduced in ceomplexity. The coeloms of cephalopds are the same complex system found in humans, whereas the hemocoels are more commonly found in annelids, or earth worms, and other primative phylums.
Yes, Chordata have a coelom. The coelom is a body cavity lined with mesoderm that forms during embryonic development and is present in most animals within the phylum Chordata. It serves several functions, including providing space for internal organs and allowing for their movement and growth.
it does not have a coelom.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
The coelom is lined with epithelium.
The presence or absence of a coelom (body cavity) is a key characteristic in the classification of animals. Animals can be categorized as acoelomates (no body cavity), pseudocoelomates (body cavity between mesoderm and endoderm), or coelomates (body cavity within mesoderm). This classification is important in understanding the evolutionary relationships and anatomical differences among animal groups.
There in the phylum Mollusca
Phylum Mollusca
Mollusca is a phylum, not a subphylum.
yes it do hav a true body cayity or a coelom.
flatworms are the only triploblastic organisms that lack a coelom
