Sharks And Minnows Simulation

This video is a 2-D simulation of Predator-Prey interactions, with reflecting boundaries. Red dots represent “Sharks”, that must eat blue dots, “Minnows”, in order to survive and reproduce. The Minnows reproduce at a constant rate, and move according to 2-D Brownian Motion. The simulation was created for the Autumn 2010 SIAMUW Math Fair at Lockwood Elementary School in Bothell, WA.

There are intentional pauses in the video inserted at “days” 4,44,74,106,141. If used in a classroom setting, the video can be paused and the number of Sharks and Minnows counted as an activity for the students.

Python Source Code to generate this simulation can be found at:
