A cineradiographic study of feeding by V. bengalensis indicates that the upper jaw is elevated at the mesokinetic joint as the mouth opens and depressed as it closes. Nile monitors are occasionally kept as pets by reptile hobbyists, but these large and aggressive lizards are a poor choice as a pet, except perhaps for very experienced keepers who can provide large enclosures. The white-throated monitor (Varanus albigularis), previously included in V. exanthematicus, also possesses blunt crushing posterior teeth. The average leukocyte count in CSF fluid is 700 cells/mm3 and can be as high as 5000 cells/mm3. Monitor lizards (Varanidae), originated over 90 million years ago in northern Asia (Bennett, 1995) and expanded during the Miocene to reach Europe, Africa and A monitor lizards bite is one of its most dangerous traits and it can cause severe pain.

The Nile crocodile (Crocodylus niloticus) and the other related species at the top end of our list were all studied by a renowned biologist who used sensitive instruments to measure the respective bite force of all members of the Order Crocodilia. This dome of plant material offers shelter for the piglets during their first vulnerable hours and days. Through theExotic Pet Amnesty Program, pet owners who are either unable to care for their exotic pets, such as Nile monitors, or who no longer wish to keep them can surrender them with no questions asked and without penalties, regardless of whether those pets are kept legally or illegally.

The turtle consume plastic bags mistaken them as jellyfish which forms their favourite food and die because of indigestion and chocking of digesting tract. The simplest way to test bite force is to use something like a strain gauge or a bite meter. Dalhuijsen,Kim et al:"A comparative analysis of the diets of Varanus albigularis and Varanus niloticus in South Africa. CRiSPs are highly conserved throughout evolution with proteins deposited in UniProt from tomatoes to turkey vultures and drosophila to dogs, so it is no surprise that they are also present in a wide range of unrelated venom systems. Although they look similar to dogs in appearance, they are more closely related to cats and civets. The lungs more closely resemble the lungs of primitive mammals and occupy the cranial dorsal and ventral cavity. Weighing 500 pounds and inhabiting the rivers edge regions around the Nile River, the Nile crocodile is the single deadliest species of crocodile in the world.

Phylum: Chordata How frequently do Nile monitors eat? They have a long, forked tongue like that of snakes that, together with a large Jacobsons organ, plays a major role in detecting prey by olfaction. Exposed, open areas are crucial habitat components as they require sufficient basking locations.

They live in long, self-made burrows or take over abandoned burrows dug by other animals, or abandoned termite mounds. The way we measure the bite force of a great white shark (Carcharodon carcharias) is not as accurate as the methods used in the crocodile study so it is much more difficult to come up with the necessary data for a good comparison.
