Wayfinding is a word used to describe how to get from one place to another, inside or outside, includes navigation skills Ants take mental snapshots of their whereabouts and remember them. When near their goal they compare what they see to their remembered snapshot and if it doesn't match they move farther or back track until it does. This method works poorly in the Sahara desert because there are not many landmarks in the desert which they can take snapshots of to help them with their route. Instead, they get around by their self-awareness of distance and direction traveled. Two additional (ego-centric) methods the ants employ is their self-awareness of distance and direction traveled which aalows them to retrace their steps accurately. This is also known as path integration.

 * Older sea turtles navigate by a "magnetic map" that includes their position and direction relative to home. Their magnetic sense combines with a natural mapping capability to form the biological equivalent of a global positioning system.
