Nile monitors require a large cage as juveniles quickly grow when fed a varied diet, and large adults often require custom-built quarters. Molecular data from contemporary and historical collections reveal a complex story of cryptic diversification in the Varanus (Polydaedalus) niloticus Species Group. "There are few lizards less suited to life in captivity than the Nile monitor. They are among the most interesting reptiles and they are beautiful animals, especially when young. Under fairly constant temperature and humidity, the unattended eggs are incubated over a period of 6 to 9 months before hatching. Estimates vary, but the expected lifespan in captivity is reported at between 10 and 20 years. This bacteria is not necessarily fatal to humans - but it can affect blood pressure and acts as a knockout punch on smaller creatures. The saltwater crocodile has the strongest bite of any animal, with a force of 3,700 PSI, making it one of the deadliest animals in the world. The detailed account on the nesting of turtle in Andaman and Nicobar Islands was reported by Murugan (2004). Steel, R. 1996.

With age, although the premaxillary teeth retain the same morphology, successive replacements result in the posterior teeth becoming rounder, shorter, and wider (Figs. Saltwater crocodiles are one of the deadliest animals in the world and are responsible for 3,000-5,000 human deaths per year. A deep, stoutly constructed skull, blunt crushing posterior teeth, and a bowed lower jaw make it easy for Nile monitors to eat hard-shelled prey such as mollusks. Snake venom CRiSPs are some of the largest ion channel blocking proteins and act on cyclic nucleotide gated ion channels [156] and l-type calcium channels [155]. With great white sharks averaging between 4,000-7,000 pounds in weight, that force pales in comparison to that generated by our number one animal when comparing pound for pound strength.

In other parts of the world, the reptiles known as marine iguanas were found, whereas it is are not found in Andaman and Nicobar Islands. When walking and foraging, the Nile monitor holds its body well off the ground, and uses its long, forked tongue to sense potential food sources. At night they may sleep on branches or submerged in water in warm weather or retreat to burrows in cooler weather. This is right on par with saltwater crocodiles, and both species tend Dentition of a juvenile African savannah monitor (Varanus exanthematicus) with sharp pointed teeth. Senckenb. The skull of the Komodo dragon seems to be adapted to minimizing stresses set up by pulling forces on the jaws rather than to exerting a large bite force (Moreno etal., 2008; Fry etal., 2009). Savannas are grasslands with scattered individual trees that do not form a closed canopy. Herpetology, a branch of zoology that deals with the study of amphibians and reptile provide significant insight of terrestrial and aquatic ecosystem.
