Web- Nile Monitor or Water Monitor (Varanus niloticus) The Nile Monitor is a widespread species found in Sub-Saharan Africa extending along the Nile valley to Egypt. The University of Chicago's Porro noted that no Tyrannosaurus rex muscle survives, so estimates for the dinosaur's bite force are based on its body size, wide skull The marine turtle also associated with specialised ecosystems such as coral reefs, seagrass meadows and seaweed beds. The tail of juveniles has alternating black and yellow bars. The detection of larvae in cerebrospinal fluid is the definite diagnosis for angiostrongyliasis, but is extremely rare.

Varanids are long-lived; geographically widespread across Africa, Asia, and Australia; exceptionally diverse in habitats (desert to swamp, arboreal to terrestrial to aquatic); and highly variable in adult body size (e.g., the pygmy monitor, Varanus brevicaudus, weighs less than 20g as an adult whereas the Komodo dragon, V. komodoensis, can weigh 150kg) (Pianka & Vitt, 2003).

They can adapt to cold weather regions by hibernating during colder months. As a result, pet monitors are commonly released into the wild. The green turtles, loggerhead and hawksbill turtles after nesting in the sandy beaches, live a pelagic phase which will last for several years (Meylan and Meylan,1998). In the more advanced monitor lizards the postpulmonary septum completely divides the lungs in the pleural cavity from the peritoneal cavity. Bacterial infection caused by a bite is the most serious concern. With age, although the premaxillary teeth retain the same morphology, successive replacements result in the posterior teeth becoming rounder, shorter, and wider (Figs. WebExotic Lizards.

"There are few lizards less suited to life in captivity than the Nile monitor. generally wanders from place to place, usually within a well-defined range. The Nile monitors high reproduction rate, diverse diet, and ability to travel over land and in fresh and saltwater allows for potential establishment throughout Florida, particularly in coastal areas dominated by mangroves or salt marshes. This family contains nearly 80 species of monitor lizards that all belong to one genus, Varanus, and Varanus shows the widest size range of any vertebrate genus. They engage in mutual tongue-licking and grooming, dewlap extension and body rubbing, and at night they often sleep together on branches. The turtle diversity in the ocean around world is fast depleting due to various natural calamities and mostly anthropogenic activities like catching them for food, entangling in fishing net, drifting fish nets, ghost fishing through marine debris, propeller inflicted wound by boat operations, collection of eggs from coastal environments, scavenging of eggs by wild as well as domesticated animals including dogs, predation of young ones by other organisms, destruction of sandy coastal habitats for developmental process, sand extraction from beaches, sea level rising and resulting coastal beach habitat modification etc. How frequently do Nile monitors eat?
