No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
The type of body cavity shared by all mollusks is pseudocoelom is a false statement. The correct answer is coelom.
A pseudocoelom is a body cavity that is not completely lined by mesoderm, distinguishing it from a true coelom. It is found in animals of the phylum Nematoda, commonly known as roundworms, as well as in some other groups like rotifers and certain species of mollusks and arthropods. This cavity allows for the development of internal organs and provides a hydrostatic skeleton, aiding in movement. Pseudocoelomates exhibit a range of body plans and lifestyles, but share this characteristic anatomical feature.
No, arthropods are coelomates
C. hemocoel
Ascaris has a pseudocoelom, which is a body cavity that is partially lined by mesoderm but lacks a full peritoneal lining like a true coelom.
pseudocoelom
A pseudocoelom is a body cavity that is not fully lined with mesoderm, while a coelom is a body cavity that is fully lined with mesoderm. The coelom provides more support and protection for internal organs, while the pseudocoelom may limit organ movement and function.
The phylum Nematoda has a pseudocoelom. This type of body cavity is not completely lined by mesoderm tissue, giving it certain characteristics of a true coelom but lacking some key features.

Mollusks are invertebrates because they do not have a backbone.
