Gerbils are naturally found in the sandy plains of Africa, Asia and the Middle East. The gerbil was originally known as a desert rat until they were commercially introduced to North America and bred as pets.
The gerbil is a small rodent, similar in many ways to by the mouse and the hamster. Gerbils have a long tail like a mouse which the gerbil is able to shed should the tail get trapped. This self defense mechanism allows the gerbil to escape predators, leaving them with just a tail.
Gerbils have sharp claws which the gerbils use to burrow their way into the sandy grounds of the desert. The gerbils are also able to use these underground burrows to get away from danger by quickly
The millipede is a medium to large sized invertebrate that is found under rocks and in decaying logs all around the world. The millipede has a long and narrow body which is made up of segments.
The millipede is from the same family as the centipede, but the millipede generally has more legs for it's body length than the centipede. The average millipede has between 80 and 400 legs, not a thousand as the name suggests.

Ducks are medium sized aquatic birds related to other aquatic birds like swans and geese. Ducks differ from swans and geese in their tendency to dive into the water in order catch their food.
Ducks are omnivorous animals feeding on aquatic plants, small fish, insects and grubs both in and out of water meaning that ducks can easily adapt to different conditions. It is because of the duck's ability to eat such a diverse amount of food both in water and on dry land that makes ducks one of the most widespread birds in the world as they are found on every continent, with the obvious exception of Antarctica.
A duck's mouth contains rows of tiny plates that line their teeth, to help th
