Finding Mates: Water Monitors' Unique Strategies And Behaviors

The water monitor lizard, also known as the Asian water monitor or common water monitor, is a large lizard native to South and Southeast Asia. It is the second-largest lizard in the world, outsized only by the Komodo dragon. Mating usually takes place in the water and is seasonal, occurring during the rainy season in India. After mating, the female leaves to find a termite hill, burrow, or another small chamber where she lays her eggs.

Water monitors use their tongues to pick up scents

Water monitors have a strong sense of smell, which they use to locate potential meals. They can smell a carcass from far away and are able to detect food from a great distance in the slow-moving waters of tidal creeks.

The water monitor lizard is the second-largest lizard in the world, outsized only by the Komodo dragon. They are native to South and Southeast Asia and are one of the most common monitor lizards in Asia. They have muscular bodies, with long, powerful, laterally compressed tails, and very long necks and elongated snouts. Their scales are thick, and usually dark brown or black with light-coloured patches.

Water monitors are semi-aquatic and excellent swimmers. They are diurnal, meaning they are most active during the day, and hide in trees, under bushes, or in cavities between rocks at night or when resting. They are carnivores and consume a wide range of prey, including fish, rodents, birds, crabs, and snakes. They also have a strong sense of smell, which they use to locate their prey.

Mating occurs in the water during the rainy season

The Asian water monitor, also known as the common water monitor, is a large reptile native to Southern and Southeast Asia. It is one of the most common monitor lizards in Asia and is among the largest squamates in the world. These monitor lizards are defined by their dark brown or black colouring, with yellow spots on their underside. They have very long necks and elongated snouts.

Water monitors are semi-aquatic and excellent swimmers, using the raised fin on their tails to steer through the water. They are diurnal, meaning they are most active during the day. They are carnivores and scavengers, consuming a wide range of prey, including fish, rodents, birds, crabs, and snakes.

The breeding season for water monitors is from April to October. After mating, the female will lay her eggs about a month later, usually in rotting logs or tree stumps. The number of eggs can range from 5 to 40, and the female's size determines how many eggs she can produce.

Females lay their eggs in rotting vegetation

After mating, it takes about a month for the female water monitor to lay her eggs. The female will head away from the tidal mangrove creeks to higher ground and find a termite hill, burrow, or even dig her own little chamber in the ground. She will then lay her eggs in rotting vegetation, usually in logs or tree stumps.

The number of eggs laid by the female water monitor depends on her size, with larger females able to produce more eggs. A single clutch typically contains around 10 eggs, but some females may lay up to 20 or more eggs.

Water monitors are semi-aquatic

Water monitors are often found in habitats with flat areas for them to dig burrows. Their burrows are often located close to rivers or streams and are partially flooded. They are known to live in close proximity to humans, utilising swampy regions of farmland or suburbs with man-made canals.

Water monitors are diurnal, meaning they are active during the day and rest at night. They hide in trees, under bushes, large roots, or cavities between rocks. They are also known to climb trees to escape predators, and if this is not enough to escape danger, they may jump from trees into streams for safety.

They are the second-heaviest lizard species in the world

The Asian water monitor, also known as the Sumatran water monitor, is the second-heaviest lizard species in the world. It is a large varanid lizard native to South and Southeast Asia and is one of the most common monitor lizards in Asia. It is also among the largest squamates in the world.

The Asian water monitor has a muscular body, with a long, powerful, laterally compressed tail. They are excellent swimmers and use the raised fin on their tails to steer through the water. Their necks are long, and their snouts are elongated. They have powerful jaws, serrated teeth, and sharp claws, which they use for both predation and defence.

The average weight of an adult male Asian water monitor is between 15 and 20 kg, while females weigh around 14 kg. The record for the heaviest Asian water monitor goes to a specimen from Sri Lanka, which weighed 32.2 kg. However, there are unverified reports of some individuals attaining weights of 75 to 90 kg.

The generic name Varanus is derived from the Arabic word waral, which translates to "monitor". The specific name is the Latin word for "saviour", suggesting a possible religious connotation. The species is also known by several common names, including Malayan water monitor, common water monitor, two-banded monitor, rice lizard, ring lizard, plain lizard, and no-mark lizard.

The Asian water monitor is a semi-aquatic species, often found in the surroundings of lakes, rivers, ponds, swamps, and various riparian habitats. They are highly adaptable and can thrive in agricultural areas and urban environments with canal systems. Their natural habitats include primary forests and mangrove swamps.

The diet of the Asian water monitor consists of a wide variety of prey, including fish, frogs, rodents, birds, crabs, and snakes. They are also known to prey on turtles, young crocodiles, and crocodile eggs. Like their larger cousin, the Komodo dragon, they will also scavenge for carrion.

The breeding season for Asian water monitors typically occurs from April to October. After mating, females lay their eggs about a month later, usually in rotting logs or tree stumps. A clutch can contain anywhere from 10 to 40 eggs, and the incubation period lasts for 6 to 7 months. The young are fully independent when they hatch and do not require parental care.

Males attain breeding maturity at a length of around 40 cm and a weight of 1 kg. Females become reproductively mature at a length of about 50 cm.

The Asian water monitor is a highly sought-after species in the international leather trade. Their skins are used for fashion accessories such as shoes, belts, and handbags. This exploitation, coupled with habitat loss, has led to their decline in mainland India. However, they continue to survive in other parts of their range due to their ability to adapt and the lower demand for the skins of larger individuals.
