And most people of aware of bats being able to find their way in the dark using an echolocation system, or sonar.

But then I found some other interesting bits of info:

Rattlesnakes have heat detectors (just behind their nostrils), which are so sensitive they can detect an approaching animal from temperature changes in the atmosphere.

And:

Migrating birds are among the most remarkable creatures, using natural navigational equipment as sophisticated as any modern plane.  In order to fly on track they rely on data from the following:

• the movement of the Sun during the day, even when it is hidden by thick clouds
• the position of the stars at night
• the strength of the Earth’s magnetic field
• checking landmarks en route and recognizing the same “home area” every year
• identifying familiar smells

Animals are so fascinating, as a family we really enjoy watching the Animal Planet Channel at home, we always learn something that is interesting about our animal friends.

Our youngest CR, wants to be a dolphin trainer when she grows up and I think that she really will do her best to become one.
