This is to demonstrate a capture / recapture experiment to estimate the population of snails in the garden. There are 20 snails in total, use the sliders to change how many are found on each day. Click the green flag and all the snails will be revealed for a second. After they disappear move the mouse around the screen to find them and mark the snails as found. They will then hide in a new random location. Move the mouse around to find snails on the second day. The total number of snails and proportion marked will be used to estimate the total population.
