Do mollusks have a pseudocoelom?
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.
Are all deuterostomes coelomates?
Coelomates are either deutermostomes or protostomes. A protostomes have spiral cleavage lie mollusks, annelids, and arthropods. A deutermostomes has radial cleavage such as echinoderms, and chordates.
Are Platyhelminthes acoelomates, pseudocoelomates or coelomates?
Coelomates.
Which would you expect to be more complex animals- coelomates or acoelomates?
coelomates
Are there other coelomates besides earthworms?
Most animals are coelomates, including humans.
What are annelids mollusks and arthropods classified as?
Annelids, mollusks, and arthropods are classified as invertebrates, which are animals lacking a backbone. They belong to the larger group called Coelomates, characterized by having a true coelom, a fluid-filled body cavity. Annelids are segmented worms, mollusks include diverse organisms like snails and octopuses, and arthropods encompass insects, arachnids, and crustaceans, all distinguished by their body structures and developmental processes.
Cephalopods are known as the?
Head-footed mollusks
Gastropods are known as the?
stomach -footed mollusks
What characteristic distinguishes arthropods and mollusks?
Mollusks compose of the large phylum of invertebrate animals known as the Mollusca. Mollusks have a mantle, mollusks invertebrate. Arthropods have jointed appendages, arthropods have segmented bodies
Are earthworms coelomates?
Yes, earthworms are coelomates because they have the "tube within a tube" body plan that characterises coelomates. More specifically, coelomates have a body cavity that is completely lined with cells derrived from the mesoderm (the germ layer of tissue found between the endoderm and ectoderm in embryonic development).
Do arthropod have pseudocoelom?
No, arthropods are coelomates
Which animal has lined gut cavity?
Animals that have lined abdominal cavities are known as coelomates. The coelom, or body cavity, is used for protecting their internal organs.
