Computer Simulation of Water Flow around Parvancorina (image) Vanderbilt University Share Print E-Mail Caption Top and side views produced by computer simulations show how water flows around the body of Parvancorina when the current is coming from the front (a), side (b) and rear (c). The arrows show the direction of the water flow and the colors represent its velocity (red and yellow are fast, blue and green are slow). It demonstrates that the flow patterns differ dramatically with each orientation. This implies that the organism had to have been mobile to feed effectively.
