Black-necked monitor lizard is the largest representative of its family, is a subspecies of the white-necked monitor lizard, grows up to 210 cm in length. This species is the largest in Africa.

There are representatives who can compete with the black-necked monitor lizard in terms of size. This species is called the Nile monitor lizard, but even it is inferior to it.

The tail is approximately the same length as the body, with very well-developed muscles. The color of the body and tail is deep, rich gray. But the head and limbs are crowned with black spots.

The throat below is also painted black, hence the name - black-necked monitor lizard. The lizard’s claws are strong, long and sharp, with them the animal digs up the ground.

This lizard can be kept at home, however, one must be prepared to provide him with all the necessary conditions for life. Since this is a rather large animal, the terrarium should be at least 270 cm long and 170 cm wide.

Black-necked monitor lizard (Varanus albigularis ionidesi).

Varan - lives on land, so special attention should be paid to the bottom of the aquarium, it is best to fill it with sand, or special floral soil. You also need to place branches and flat stones in it, since they like to climb and warm up on stones. And, of course, you need to create a small pond that will always be filled with fresh water.

Range of black-necked monitor lizard

Numerous black-necked monitor lizards populate the tropical and subtropical forests of Africa, with the exception of Madagascar. Distributed also in Australia, Asia and New Guinea. Easily adapt to various climatic zones, therefore, they are found in sandy deserts and in moist forests.

Black-headed monitor lizard, however, like all types of monitor lizards, is not picky in food.

Features of the nutrition of monitor lizards

The food is absolutely not picky. They can enjoy carrion or small lizards, but, in general, they use everything that can move. Adult representatives of these monitor lizards can overpower large rats, chicks, even rabbits and medium-sized piglets. Insects also often become a lunch of monitor lizards - locusts, large Madagascar cockroaches, etc. They feed, on average, twice a week, however, young individuals eat 5-7 times a week.

They can not yet use rodents and other similar animals, but they are happy to eat crickets, Khrushchakov, moths, and also worms.

In search of food, lizards are helped by sight and acute sense of smell. They have a well-developed Jacobson's organ, which is located in the nose, it is rich in olfactory receptors. When capturing prey, the monitor lizard closes the jaw and shakes the prey, even hit it on the ground.

During gestation, the female appetite of the black-necked monitor lizard increases, they consume much more food, in artificial conditions it is better to add calcium to the main diet.

Breeding and breeding black-necked monitor lizards in captivity

Lizards do not form pairs, they can mate with several females at once. As soon as the female becomes pregnant, the mating season for the male is over. When kept in a terrarium, it should be isolated from it, since it can have an irritating effect on a pregnant individual, which does not have a very beneficial effect on the development of eggs.

Forty days later, the female will be ready to lay eggs, for this she will look for a secluded place in advance, the temperature in it should be about 30 degrees.

The debugging process itself takes place in several stages and can take an entire day. The female takes breaks from time to time and leaves a shelter to drink water. In clutch there can be up to 70 eggs. In conditions of home breeding, it is better to place the eggs in the incubator for 4-5 months. After that, small black-necked varanchiki will be born.

International scientific name

Varanus albigularis Daudin, 1802

White-necked monitor lizard source not specified 618 days (lat. Varanus albigularis) - a species of lizards from the family of monitor lizards. This species was previously classified as a subspecies. Varanus exanthematicus. The specific name is translated as lat. albus - “white”, lat. gula - "throat."

Description

Head on top of gray or brown, throat significantly lighter. The nose is dull. The body is covered with dark rosettes with cream centers in adults, the rosettes are much less expressive and can give the illusion of stripes around the chest. Claws are sharp, bent back. Size varies by geographic location and subspecies. Males are usually larger than females. The body length excluding the tail is more than 50 cm, the total length is usually from 0.85 to 1.5 m. The body weight of males of reproductive age averages from 5 to 8 kg, while females from 4.5 to 6.5 kg. Animals in captivity can become extremely obese, with a body weight of more than 20 kg. Cubs are about 12 cm long and weigh between 20 and 25 grams.

Lifestyle

Mostly a land animal, which spends some time on trees, especially during breeding and resting. He actively hunts both on trees and on the ground, and also uses trees as shelters from midday heat and enemies, as well as at night. In summer, it is active throughout the daylight hours, with the exception of noon, when the ambient temperature reaches extreme values. In the winter months, the animal is much less active. Lizards generally stay overnight in their shelters during the colder months, but often their heads protrude from the entrance to the shelter. Winter inaction is the result of a lack of affordable prey, as an experimental increase in food supply led to a 30-fold increase in activity.

Nutrition

Being an active predator without a clear food specialization, the white-necked monitor lizard eats everything that it can catch. During the rainy season, snails, millipedes, beetles and grasshoppers form a large part of his diet. When the migration flows of insects are especially large, lizards should only move a short distance to get enough food. However, snakes are the preferred prey item. In Namibia, cobras, vipers and snakes are most commonly found in the diet of white-chinned monitor lizards. Only hieroglyphic pythons seem to be rare in the diet, most likely due to the huge size of adults. Even the just-hatched calves of the white-chinned monitor lizards attack snakes. These monitor lizards also prey on the eggs and chicks of birds nesting both on the ground and on the trees. The largest bird eaten by this lizard during a ration study in Namibia was barn owl. Farmers also report that lizards eat chickens. In Namibia, white-necked monitor lizards rarely ate mammals, even though they often shared underground shelters with Cape earthen squirrels, and their daily activity approximately coincided.

Natural enemies

Like other large species of monitor lizards, the white-necked monitor lizard has few natural enemies. Not very large individuals can sometimes be attacked by large birds of prey, such as a war eagle, because these lizards are not as flexible and aggressive as, for example, Nile monitor lizards. Larger predators, in particular crocodiles and big cats, can eat white-chinned monitor lizards from time to time.

Striped monitor lizard

Striped monitor lizard, or water monitor lizard (Varanus salvator) is a species of lizards endemic to Southeast and South Asia. These are the most common lizards in the Asian part of the world. Their range varies from Northeast India, Sri Lanka, the Malay Peninsula to the islands of Indonesia. Water lizards are large lizards that reach 150-200 cm in length and weight up to 20 and more kg. They have a muscular body and powerful tail. The sharp sense of smell of the striped monitor lizard helps him identify and overtake prey in kilometers from the habitat.

Arizona Venom Tooth

Arizona Venom Tooth, or Vestment (Heloderma suspectum) is one of two species of poisonous lizards in the world that lives in the deserts of Chihuahua, Mojave and Sonora in northwestern Mexico and the southwestern United States. These lizards are dark brown in color with spots of yellow, orange, and pink. The body length of an adult can be 50-60 cm. The vest has an extremely painful and poisonous bite that can kill a person. An Arizona Toothpiper spends 95% of his life in underground burrows and appears only to find food and bask in the sun. The lizard has a large supply of fat in its thick tail, which allows it to hold out for several weeks without food.

Varan of Salvador

The lizard of Salvador, or the crocodile lizard (Varanus salvadorii) is a large species of monitor lizards native to New Guinea. This is the largest lizard on the island. The lizard of El Salvador has an exceptionally long tail (about two thirds of the total body length). Some specimens of the crocodile monitor lizard exceeded the length of the Komodo monitor lizard, which is officially the largest lizard on Earth. Varan of Salvador lives in coastal rainforests and swamps of mangroves in the southern part of New Guinea. It feeds on carrion, birds, eggs and small mammals. The species is threatened with extinction due to poaching and deforestation.

White-necked monitor lizard

White-necked monitor lizard (Varanus albigularis) is one of the largest species of lizards in Africa. It occurs in the southern, eastern and central regions of the continent. The average weight of an adult varies from 3 to 5 kg in females and from 6 to 8 kg in males, large males reach 15-17 kg. The length of the body can reach 150-200 cm. White-necked monitor lizards prefer to live on trees away from water. They are known to be very territorial, and in case of a threat they bite, scratch or whip their powerful tail.
