Examples of Crawling Animals

Animals that crawl are called reptiles, which also show a series of characteristics in common. The word reptile comes from the term creep, which means to move by crawling on the ground. For example: turtle, crocodile, alligator.

Reptiles areVertebrate animals with scales composed of keratin. Most of them are adapted to terrestrial life, however some also live in water. The vast majority are carnivores. They have breath pulmonary and a double-circuit circulatory system.

Some reptiles achieve move without legslike snakes. The locomotion of snakes depends on various methods, depending on the species and the moment. For example, when a snake is about to attack, it cordons off and uses its energy to move rapidly forward, surprising its dam.

Reptiles are ectothermic, that is, they depend on environmental conditions to maintain their temperature. For this reason, in general each species of reptile belongs to environments with very similar characteristics, since they can only survive within a certain range of temperatures. Reproduction is internal, that is, the male deposits the sperm inside the female's body.

Examples of crawling animals

1. Chameleon. There are approximately 160 species. They are characterized by their ability to change color depending on where they are. Chameleons are predatory reptiles of worms, grasshoppers, locusts, flies and others insects.

2. Alligator. Its 14 different species are found in Africa, Asia, America and Australia. Although it is a land animal, it congregates in habitats freshwater (rivers, lakes and wetlands). To achieve the body temperature you need, as soon as the sun rises it remains motionless in an area of ​​clear land, to receive its heat.
3. Komodo dragon. Sauropsid that lives on islands of central Indonesia. It is the largest lizard that exists. Its average length is between two and three meters. Its average weight is 70 kg.

2. Desert iguana (Dipsosaurus dorsalis). It is very numerous in deserts from Sonora and Majove (United States and northwestern Mexico). The color of each individual affects the ability to obtain the necessary heat from the rays from the sun: dark-colored individuals absorb 73% of the visible light and therefore the heat of the Sun. Light-colored individuals absorb only 58% of visible light. One of its methods of stabilizing body temperature is the regulation of peripheral blood flow: the vessels contract and therefore, they decrease the exchange of heat, or they expand (increase in size) so that the exchange of heat increases in turn. hot.
3. Green lizard. A species of lizard (reptile) of the family Teiidae. It is located in an ecozone that spans the Argentine, Bolivian and Paraguayan Chaco. It can reach 40 cm long. It is characterized by having only four toes, unlike all the other Teiidae reptiles, which have five.
