Abstract
A sea hare (Aplysia brasiliana) swims via a form of jet propulsion which involves folding over a pair of parapodia to form a funnel and squeezing water out the posterior end of the funnel. We develop a simple model of this swimming mechanism, then calculate the mean thrust and instantaneous speed in a particular instance. We also discuss aspects of its mechanical efficiency and possible model extensions.
