In this video, a competent (i.e., ready to settle) mussel larvae is placed in a water filled channel. On one side is filtered water (left) and on the other, water that previously had an adult mussel soaking in it (right). After searching around for a bit, the mussel larvae swims towards the water that previously had an adult mussel in it, demonstrating the larvae's chemosensory abilities. See the "larval behavior" research section for more information!
