Crocodiles and Alligators | Compare and Contrast | Third Grade

Listen to this article on crocodiles and crocodiles and explore the concept of comparison and comparison

Crocodiles and crocodiles are huge and scary reptiles. They have tough scaly skin, they are cold blooded animals, so they are classified as reptiles. This means that as the temperature of the air rises the body temperature rises, and as the temperature of the air decreases the body temperature drops.

Crocodiles and crocodiles fill eggs in sand and mud until the baby gets hatched. Very young crocodiles and crocodiles eat worms and insects. Adults can eat mammals and even attack humans

Crocodiles and crocodiles move the tails to the left and right to swim. Because they need to breathe in air, their nose and the tip of their eyes can always be seen outside the water.

The main difference is that there is a narrow nose to reach the tip of the crocodile even if the mouth of the crocodile is closed. I still see the teeth under the fourth. On the other hand, the crocodile's nose is wide and dull. When the mouth of the crocodile is closed, I can not see the teeth under the fourth.

Another difference between crocodile and crocodile is habitat. Crocodiles are found in wetlands, lakes, rivers in tropical regions of Africa, Australia, Asia, Madagascar, South America. Alligators are only in two freshwater zones: American crocodiles can travel from North Carolina to Florida and from the west to Texas southeast of the United States. Chinese crocodiles live in the Yangtze River valley in China

In addition, crocodiles move less slowly than crocodiles, not aggressive. It is not that big. As we all know, crocodiles grow to 23 feet. Crocodile grows to 15 feet long

The easiest and quickest way to judge the difference between an alligator and an alligator is to compare two noses. The crocodile has a relatively wide nose, and the crocodile has a narrower nose. Think about an alligator as a crocodile with 'U' shaped nose and 'V' shaped nose. Another difference between the two is the position of the teeth. In the crocodile, the upper jaw is larger than the lower jaw, the fourth big tooth of the lower jaw is suitable for the upper jaw, it does not appear when the mouth is closed. In the crocodile, the width of the upper jaw and the width of the lower jaw are almost the same. As a result, the fourth largest tooth on the mandible fits outside the maxilla, making it easier to see. In general, crocodiles tend to prefer fresh water, but crocodiles tend to like salt water. These differences are not strict rules, and everyone can adventure beyond their favorite type of water in a short time.

Crocodiles and crocodiles are easily distinguished by teeth. The fourth big tooth of the crocodile jaw is inserted into the socket of the upper jaw and can not be seen when the mouth is closed. This does not happen to crocodiles. Crocodile has 74 to 80 teeth in one mouth. They are exchanged when they are exhausted. Crocodiles can pass through 3,000 teeth in their lifetime. Crocodiles are carnivorous. They have a very strong squat that can damage the shell. They eat fish, snakes and other invertebrates, birds, frogs, mammals to the waters. They grabbed and grabbed their prey with sharp teeth. They swallowed small prey all over. When prey is large, it is divided into small and easy to handle. If it is very big they rotate over the long axis of their body to bit it and then tear off the parts that are easy to swallow.
