Abstract: Fertilized eggs of Ascidia ceratodes hatch in about 24 hours. Resulting free swimming larvae settle and begin metamorphosis 1-2 days later. Development of the major organs involved in filter feeding occurs 36-48 hours after settlement. Feeding begins at 60-72 hours. Spontaneous contraction begin at about 48 hours and contractions in response to physical disturbance at 72 hours.
