And Keep Your Eyes Wide Trivia Quiz

The elephant is one of the biggest land animals and the wrinkled skin around the eye should have helped you to identify it. Elephants are seen in Africa, where there are two types - those that live in the savannah, or grasslands, and a smaller forest elephant which lives mainly in regions near the River Congo.

The Asian elephant is smaller than the savannah elephant, and herds are found in several countries in the region, mainly in India and Sri Lanka.

This is an ostrich, which has a regular bit of trivia about it, as it has an eye which is bigger than its brain. The ostrich is native to Africa and is the fastest running bird on earth. It is flightless, but does use its wings to change direction when running, for display in courtship and to communicate with other ostriches.

Australia does have wild ostriches, which have escaped from farms where the birds are bred for their meat.

To be more specific, this is the red-eyed tree frog - no prizes for guessing where it got that name. It is found in Central and South America and its bright colouring helps with camouflage in the forests where it lives. You can just see a bit of its webbed feet, which help it to cling to leaves and branches.

It is a nocturnal frog, meaning that it comes out at night, and lives on many different kinds of insect including flies, mosquitos and crickets.

This is an animal you are more likely to see in the countryside, as this eye belongs to a horse. Most horses have been tamed and are used for riding, racing and, for some breeds, working.

There are some truly wild horses, particularly in Mongolia, while there are others in the wild which are called 'feral'. This means that they are descendants of tame horses which have become wild over many years. The mustangs found in the United States of America are classed as feral, for one example.

This is a picture of a golden eagle, but all eagles have excellent eyesight. In fact, humans with good vision are often described as 'eagle-eyed'. Eagles can see prey moving from around three miles away and can fly fast too, giving them a good chance of catching their meal.

There is debate about which eagle has the best sight, with the bald eagle and golden eagle being the top choices. Eagles are not the only ones, though, as other birds of prey, such as hawks and falcons, also have exceptional eyesight.

This is an unusual view of a dragonfly, but it does give you a good look at its eyes. It is a type of insect, which you are likely to see hovering over a pond while hunting for insects. The eyes are very large and are called 'compound', meaning that they contain a large number of light collecting cells.

Dragonflies are found in many parts of the world although most of them live in tropical regions. There are far fewer species in the temperate (cooler) parts of the world.

Clicking on the photo will make the chameleon's distinctive eye even clearer. The chameleon is a type of lizard, known for being able to change its colour to blend in with its surroundings. The type of change depends on the species of chameleon, with some being able to change colour completely while others can only vary the brightness of their skin.

A chameleon's eyes are different from most animals as they work independently. This means that each eye is sending a different image to the animal's brain. The chameleon can adapt, though, so the eyes work together, particularly when hunting prey. Most chameleons live in southern regions of Africa and Madagascar, but some are found in Asia and southern countries of Europe.

This is an animal you're much more likely to see on a farm than in the wild, although domesticated pigs do have wild cousins in wild boars. Farm pigs have been bred for food, with bacon, pork and ham all being types of meat from pigs.

Unlike some of the other animals in the quiz, a pig's eyes are quite small and its eyesight is poor. On the other hand, its sense of hearing and smell is very good.

These eyes belong to the snowy owl, which lives in the Arctic regions of the world. The male has mostly white feathers while the female has much more brown plumage. They feed on small mammals with lemmings, a type of vole, being the most common.

Unlike other owls, snowy owls are active during the daytime as well as the night.

The stripes probably gave this one away as this eye belongs to a zebra, another animal which is found in Africa where they form large groups, called herds. The pattern of the stripes is different for each animal so individuals can be identified in studies.

Zebras live mainly in southern regions of Africa. Although they have some similarities to horses, zebras are very difficult, if not impossible, to tame due to their natural instincts and aggressive nature.
