Insects known as animal species, amounting to the most. There are more than a million species we know. Insect body sizes ranging from small sizes of up to flea beetles the size of your palm. Insects have no bones, but a hard protective order on the outside called eksoskeleton.
All kinds of insects in general have the same body structure. Insects have three body parts: head, chest (thoracic), and stomach (abdominal). 
There are eyes in the head, jaw and sensory organs. In the chest there legs and wings. Insects have six legs and many have one or two pairs of wings. Abdomen is made up of the stomach, reproductive organs, and respiratory tract, called spirakula. Spirakula change lung function. As a result, the insect's body can not grow larger. If the body becomes bigger, the insect will die because the air can not be channeled through the body quickly.
Ants, termites and bees are social insects. They are members of a colony. Center of colony life is in a laying queen. While serving only males fertilize the new queens which fly elsewhere to establish new colonies. After mating, males will die. Social insects serve to build a complex structure of the house. Wasps made a nest of paper from plant materials in the chew. Honey bees build nests made of geometric cells of wax. While ants and termites make their nests from the ground.
Generally insects have two pairs of wings, except the worker ants and fleas. Beetles have wings, but not visible. Front wings transformed into the hard shell covering a soft rear wing, which used to fly.
Several kinds of insects, such as the African desert locust, is a very harmful pests. Locust invasion can damage the mob big fields within just a few hours. However, many types of insects that are beneficial to humans. Without the bees and other flying insects, pollination is unlikely to flower and produce fruit trees difficult.
The world record-breaking insect has exceptional. The sound of crickets can be heard at 500meter. Queen termite can live up to people's age, ie up to 50 years. Many species of insects can lift or drag objects that weigh 20 times their own weight. The largest insect is a winged butterflies Queen Alexandra bird measuring 20 inches stretched.

Amphibians are among the smallest group of vertebrates, with the number of only 3,000 species. Like fish and reptiles, amphibians are cold-blooded animals. This means that amphibians can not regulate his body temperature. For that, amphibians need the sun to keep warm. Initially amphibious life began in the waters and make breathing with gills. Along with the growth of lung and legs develop and amphibians can walk on land.

Amphibians are found throughout the world except the poles. They occupy a number of habitats as varied as the rain forest, ponds, and lakes. They are also in the grassy area on the slopes of high mountains, even in the desert.
Although adult amphibians can survive long dry periods, they were generally requires moist places such as rivers and ponds. Tropical rain forest region is humid, a lot of frogs can survive without a permanent water source. As cold-blooded animals, amphibians are not active in cold conditions. In this condition they do hibernate, usually in the mud at the bottom of the pool.
Difficulty distinguishing the crowd of frogs and toads. In general, smooth-skinned frogs and more are in the water. Frogs and toads prey on insects and other small animals. They stay quiet place to wait for prey to pass. Some species use the tongue long and sticky to catch prey.
Amphibian breeding season often chaotic place. Amphibians males and females gather together in large numbers. After the egg, usually no longer care for amphibian eggs. Only a few types of amphibians that protects the egg.
Amphibians such as salamanders largest china and giant cane toads are not a lot of enemies. Generally small amphibian species rely on camouflage or escape predators when threatened. There are also amphibians that rely on the striking skin to frighten the enemy.
There are types of amphibians that have poison. Poisonous frogs from South America to have colors that stand out as a sign of danger pemangsanya. Very strong poison frogs 'poison gold' owned dart frog from Colombia for example, may be killing about 1,000 people at once.
