Abstract

The spacing and orientation of sipons of Styela plicata (Lesueur)in swift and slow currents were examined. Within aggre­ crates, the siphons were spaced farther apart in slow currents than in swift currents. The siphons were not horizontally oriented but were vertically oriented in slow currents. The adaptive values of spacing and orientation under different currents are discussed.
