(last updated on 2016/01/14)Abstract:
1. 1. The geometry of keyhole limpets suggests that they should experience water flow through the mantle cavity driven by environmental currents. 2. 2. In a living Diodora aspera even a slight ambient current (5 cm/sec) increases the rate of transport of water through the mantle cavity about three-fold over the still-water pumping rate. 3. 3. In a model limpet (using a real shell) the magnitude of this increase proves primarily dependent on the speed and secondarily on the direction of the environmental current. 4. 4. While the direct cost of normal pumping by these animals is trivial, induced flows may substantially decrease the fraction of the dissolved oxygen which the limpets must extract from the water passing through them. © 1978.
