Enteropneusta (acorn worms) are primarily deposit feeders, ingesting sediments and extracting nutrients, while Pterobranchia (pterobranchs) are filter feeders, using their tentacles to capture food particles from the water. This feeding method is a key distinguishing characteristic between the two classes within the phylum Hemichordata.
