Iguana Vs Monitor Lizard
Iguanas
Depending upon the species, there are a variety of scales found in iguanas that cover specific areas of their body. On the dorsal trunk of an iguana’s body, the scales tend to be more tightly packed and thicker than those on the ventral sides.
At the same time, some round tuberculate scales large in size are scattered around the neck’s lateral region overlapping smaller skills. Depending upon the type of the species of Iguana, these scales are not always recognizable from a close distance and maybe a variety of colors.
On the Iguana chick, it has round but large scales known as subtympanic shields. Adding to this, iguanas use visual signals with other lizards of the same species to communicate. They also have very clear visions, which also enable them to see colors, movements, shadows, and shapes from very long distances.
This visual ability and equity help them not only run away from predators but also to navigate through crowded forests dense with bushes and shrubs. Their Sharp vision also helps to forage for food.
Monitor Lizard
Do you know that monitor lizards carry the highest standard metabolic rate compared to all extant reptiles? They are also popular for their active pursuit hunting skills reminiscent of similar size lizards or mammals. Being highly territorial, they are known to maintain large territories to live and breed.
Also, numerous activities have been done to study these lizards’ metabolic capacities due to being highly active. Most reptiles come with a three-chamber heart, but when we talk about the nature of monitor lizards, it’s like pythons and boas’ seats.
Monitor lizards tend to have a well-developed ventricular septum. During systole, it completely separates the systemic and pulmonary sides of the circulatory system to enable quick distribution of oxygenated blood throughout the body without flooding the Iguana’s lungs with high-pressure blood.
This heart system of monitor lizards helps them create a mammalian equivalent pressure differential between the systemic circuits and the pulmonary circuits.
What do You need To Know About Iguanas?
Apart from sharp vision, iguanas also carry a parietal eye sensitive to any change in illumination. It helps them signal their pineal gland to learn and indicate the day and night cycle change. They also carry a photopigment known as parapinopsin that is sensitive to the difference between day and night.
Therefore, iguanas not only have beautiful spikes and scales on their body but also have a keen sense of eyesight that enables them to forge food, run from predators, and navigate with ease. They also use their eyes to signal and communicate with other iguanas or lizards of the same species.
Also, they are popular for shedding their tails tailor some part of that when they feel threatened by predators. In lizards’ worlds, clearing part of the tail allows them to escape easily in the wild while distracting the predators.
Do you know that the Iguana that hails from South and Central America is sometimes known as the chicken of the trees? Iguanas from Florida are known as a pest. Hence, iguanas are great swimmers; the Marine iguanas in the Galapagos Islands are great at diving and swimming away from predators. Marine Iguana usually digs their burrows near a water river bed or water sources.
