Question

Which of the following lizards is limbless and serpentiles?
A.Hemidactylus
B.Ophiosaurus
C.Heloderma
D.Varanus

Answer 1

Hint: Few vertebrates have established limbless, reduced-legs. Reptiles have evolved into limbless species in a variety of situations– rodents, amphibians, and legless lizards. Legless species of snakes and lizards have undoubtedly developed in such a way that they could travel very quickly submerged and in water.

Complete answer:
Glass lizards, often referred to as glass snakes, are an Ophisaurus family, so named since their tail is completely destroyed. The glass lizard, Ophiosaurus, is distributed in South Eastern North America and expands to about 105 cm. The body and head of the creature collectively account for only 30 to 35 percent of the overall length. These have no limbs but are visually distinguishable from a snake with its paws, eyelids, non-expandable teeth, as well as the reality that the spikes on the lower and upper sides of the body are also of comparable size. They do have the capacity to inhibit predation by falling off part of the tail, which would split into too many parts, like glass. The tail continues mobile, frustrating the predator, whereas the lizard goes motionless, enabling a potential rescue. Their diet mainly consists of arthropods, with large mammals feeding snails and small animals. The diets are restricted by their failure to loosen their jaws. A few glass lizards give birth to offspring, but many of them produce eggs.
So, the correct answer is option (B).

Additional Information:
The root of the Hemidactylus is still mysterious because its higher level of phylogenetic is not very well established. In addition, most of the varieties need to be discovered in this group. Usually, the species are reported as house geckos, attributed to their willingness to adapt and coexist among humans, and can usually be accessed in human habitations. Like most other gecko species, the organisms in the genus Hemidactylus are capable of interacting with different vocalizations. Heloderma or beaded lizards are huge, muscly, slow-moving vertebrates that favor semiarid environments. They have short tails that are used as fat storage organ systems. Beaded lizards are poisonous. The toxin is typically used mostly for a defensive strategy, instead of for incapacitating bait, and the lizard should munch the victim to function the toxin into flesh. Monitor lizards are massive lizards in the Varanus subspecies. They are native to tropical Africa, Asia but are now as well found as exotic species in the United States. Approximately 80 species have been reported. Monitor lizards have long necks, fierce tails and claws, and very well-developed legs. Much of the monitor species are terrestrial, but gale and semi-aquatic monitors are also regarded.

Note:The evolutionary process of changing lizards into limbless forms outcomes in three major areas: the reversion of the limbs is conducted out gradually, by shrinking the size of the limbs and decreases the number of fingers, the replication of the vertebrae creates the widening and improves the agility of the trunk.
