What is the symmetry of a lancelet?

Lancelets, which are small marine organisms belonging to the subphylum Cephalochordata, exhibit bilateral symmetry. This means that their body can be divided into two mirror-image halves along a central plane. This symmetry is typical of many chordates and is crucial for their streamlined shape, aiding in movement through water. Additionally, the bilateral symmetry in lancelets reflects their evolutionary position within the broader chordate lineage.
