Koalas:
When a baby koala is born, it is only the size of a jelly bean! The baby is called a joey and it is blind, naked and earless. Once the baby is born, it will make its way to it’s mother’s pouch. The koala has a thick fur which protects them from both the heat and the cold. Koalas are lazy animals which spend as many as 18 hours a day napping and resting. When a newborn koala latches onto a nipple of its mothers pouch, the nipple swells so much in the joey’s mouth that it cannot be separated from their mother which is their food source.

Nile Crocodiles:
Crocodiles are cold-blooded like all other reptiles. Even though they are cold-blooded, crocodiles like to keep their body temperature
constant. To control their temperature, crocodiles bask in the sun during the day, cool off during midday by having a dip or a rest in the shade and spend the night mostly submerged under water. Crocodiles have webbed feet for swimming but they seldom use them. Nile crocodiles live around the
lakes, marshes and rivers of Southern Africa. They eat stones to help them to digest their food.

Adelie Penguins:
Adelie penguins can live up to 20 years. A group of penguins is called a colony and in a colony, there can be up to as many as 100 to 250,000 pairs of birds. They build nests by scooping areas out of the ground. They then line the depression with stones. The stones help to keep the eggs dry and warm by keeping them off the ground.

Bald Eagles:
Bald Eagles builds their nests on top of tall trees to keep the eggs safe. The parents will come back year after year to the nest and they will add twigs, sticks and grass each time. It can fly up to 10,000 feet high and they have a awesome eyesight which lets them see a fish from a mile away. When they have spotted their prey, they will drop down to about 100 miles per hour and glide above the water and use their feet to catch the prey. They can live up to 35 years or more.

Bottle Nose Dolphin:
Dolphins look like fishes but they are actually mammals and breathe through lungs just like us. This species of dolphins are called Bottle Nose dolphins as their noses are shaped like bottles. Bottle nose dolphins can be found in temperate and tropical waters. Having little smell or non at all, they depend on their sharp sense of hearing to make up. They usually hunt in groups, once in awhile, they will hunt alone. The diet of a dolphin is mostly fish but they also eat shrimps. They will swallow their food whole.
