The hydrodynamics and kinematics of the appendicularian tail underpin peristaltic pumping.

“Flow tracers consisted of live, unicellular microalgae. Rhinomonas reticulata was used for observations at low magnifications (4×) and Isochrysis galbana was used for observations at high magnifications (40×).” “Our micro-videography confirms that the beating tail in O. dioica acts as a positive displacement peristaltic pump when filtering” “Temperature had a significant effect on tail beat frequency, which increased by 366% from 5 to 25°C.” “Likewise, inlet particle speeds increased with increasing temperature”
