How Animals See

Not all animals see the world in the same way humans do. They can see different colours, amounts, and some can even see by other things than light.

Snakes Snakes can see fairly well but they can see motion better than unmoving objects. Many can also see heat signals from warm objects. This is called infrared sensing. – Ex) Rattlesnakes

Horses Horses have eyes on the sides of their head allowing them to have much more peripheral vision than humans have. This allows them to see predators coming from almost any direction. Their only blind spots are directly behind them and right in front of their nose.

Deer Deer also have excellent peripheral vision but they only see in green, blue and purple. They can also see UV light.

Insects Many insects, such as dragonflies, grasshoppers and spiders, have compound vision. This means their eyes contain many sections. This gives them almost 360⁰ vision Honeybees have compound vision as well but cannot see the colour red

Eagles Eagles and other birds of prey have the sharpest eyesight in the animal kingdom They can spot small animals on the ground from high up in the sky

Do You Have Eagle Eyesight? One person needs to hold up the paper with the eggs and one end of the tape measure, while you stand 20 metres away with the other end of the tape measure. Walk slowly towards the strip of paper and when you can see two cracked eggs, stop in your tracks! Measure the distance between where you stopped and the paper. Swap over and see how close your friend needs to be before they can see the cracked eggs. An eagle can tell from 18 metres away whether a speck is just one dot or two dots that are very close together. Most humans with good vision can distinguish two dots from about 6 metres away.
