Do lancelets have appendages

Lancelets, which belong to the subphylum Cephalochordata, do not have appendages like limbs or fins. They are small, fish-like marine animals characterized by a simple body structure, featuring a notochord, a dorsal nerve cord, and pharyngeal slits. Lancelets primarily rely on their body for locomotion, using their muscular contractions to burrow into the sand or swim. Their lack of appendages is one of the distinguishing features that sets them apart from more complex vertebrates.
