The observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.
<h3>What are lophotrochozoans?</h3>
Lophotrochozoans represent a well-defined group of animals that are characterized to be protostome species.
These animals (lophotrochozoanns) include different taxonomic groups such as, for example, worms or annelids, mollusks, brachiopods, Platyhelminthes, etc.
The lophotrochozoans represent a polyphyletic taxonomic group from a non-strictly evolutionary point of view but instead, composed of species that have a structure referred to as lophophore, a collection of ciliated tentacles surrounding the mouth.
In conclusion, the observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.
