From Latin lacartus, a lizard it’s a reptile terrestrial belonging to the order Saurians. It has an oval head, a large mouth full of sharp teeth, a long body, four short and thin legs and skin covered with lamellae like scales.
Lizards are usually between five and eight centimeters long, they are very agile and, in most cases, they feed on insects. As they are harmless to Humans, it is a very valuable animal for the farming as it helps fight pests.
The notion of lizard can be understood as the clade of reptiles that includes species such as the iguanas, the chameleons, the Lizards and the geckos. Lizards, snakes, and blind shingles make up the order of the Flaky (Squamata).
For instance: “My son went to the zoo and came back fascinated with lizards”, “My neighbor has a huge lizard as a pet.”, “I love animals, but I must admit that lizards repulse me”.
The chameleon It is one of the most surprising lizards since it has the ability to change Colour according to the circumstances. In this way it manages to blend in with the environment and can go unnoticed in the presence of a predator. Another notable feature of the chameleon is that it can move its eyes independently of each other.
The Komodo dragon It is the largest lizard in the world: it can measure up to three meters and weigh about 70 kilograms. This size allows them to feed on small mammals and birds.
The lizard’s tail
The lizard’s tail is usually quite long, as is its body but unlike its legs. One of the most fascinating characteristics of this group of animals is their ability to let its tail behind, a very effective resource to defend itself from other species in times of danger.
The utilities of the lizard’s tail are many, as it allows it to maintain balance while running, escape from predators, climb, hang, and swim. During times when food is scarce, on the other hand, some of these animals have been known to eat their own tails to cope with death, as it provides them with the Energy they need to stay on their feet.
The lizard’s tail is generally more striking and shiny than the other parts of its body, so its predators natives focus on it so as not to lose track of them; In the face of a threat, detaching the tail can serve to lighten the pace and confuse its hungry hunters long enough to escape.
Each species of lizard has particular restrictions regarding this mechanism of defending: some can only get rid of their tail during youth and others throughout their lives; certain species have the ability to leave the entire tail, unlike those that can only lose a part of it. It is believed that the larger and slower the lizard, the longer the length of tail it can lose.
Two mechanisms of tail loss are known to be used by the lizard:
* intravertebral autonomy: given the presence of certain zones weak in its vertebrae that reach the connective tissue that surrounds the tail and its muscles, if a predator catches the lizard’s tail, it contracts the muscle that surrounds it with enough force to break the vertebra and be able to escape;
* intervertebral autonomy: the lizard breaks its tail inside the vertebrae, which reduces the chances of it regenerating.
