Tentaculita is an extinct class of lophophorates ranging from the Early Ordovician to the Middle Jurassic. They were suspension feeders with a near worldwide distribution. For a more thorough discussion, see Tentaculites.

The presence of perforate septa and "septal necks" has been used to argue for a cephalopod affinity, whereas the shell microstructure, notably the presence of punctae, points to a brachiopod relationship,[5] and preserved musculature suggests a relationship with bryozoans.[6]
