(Lophophores) Ectoprocts and Brachiopods share the following:____________- ciliated crown of tentacles around mouth for feeding U-shaped ___________ canal Absence of a distinct ______a coelom
lophophore; alimentary; head
Lophophores, Ectoprocts, and Brachiopods share the following characteristics:
– Lophophores: A crown of ciliated tentacles around the mouth that is used for feeding.
– U-shaped digestive canal: Both Ectoprocts and Brachiopods have a U-shaped digestive canal, meaning that the mouth and anus are located close to each other.
– Absence of a distinct coelom: Both Ectoprocts and Brachiopods do not have a true coelom, which is a fluid-filled cavity surrounded by mesoderm. Instead, they have a pseudocoelom, which is a partially lined body cavity that is formed from mesoderm and endoderm.
Therefore, all three of these groups are considered to be part of the larger group of animals called Lophotrochozoans, which are characterized by the presence of a lophophore and/or a trochophore larva.
