They can stand on their back legs and tail to gain a better view of the surrounding terrain. This behaviour, known as "tripoding", is quite common to all monitors large and small. Perenties are fast sprinters, running using either all four legs or just their hind legs.

Perenties generally forage for their food, but are also known to wait for small animals to come to them. Prey include: Insects Reptiles, including their own kind Birds and birds' eggs Small mammals Carrion Large adults can attack larger prey, like small kangaroos.

More people are killed by vending machines than by Australian saltwater crocodiles

the Estuarine, a saltwater crocodile

Johnsons, a freshwater crocodile

Both are found in the hot, tropical northern part of the continent.

The Estuarine crocodile, while it can live in salt water, is able to go quite far up river into fresh water. It is one of the most dangerous of all the crocodile family, being the biggest and heaviest. It grows to between 4 and 7 metres long.

The Johnsons crocodile lives mostly in freshwater, but can also live in salt water. It grows up to 3 metres long. It is considered to be dangerous even though it is not known for attacking humans.

There are about 140 species of snakes in Australia. The most poisonous land snake is the inland tiapan found in south-western Queensland and north-eastern South Australia. Tiger snakes, death adders, copperheads, brown snakes, and red-bellied black snakes are all also highly venomous.

A nonpoint source delivers pollutants indirectly through environmental changes.

Nonpoint sources are much more difficult to control.

Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes.  

Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates.  In excess levels, nutrients over stimulate the growth of aquatic plants and algae.  Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.

Pollution in the form of organic material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures.

    Pathogens are another type of pollution that prove very harmful.

Three last forms of water pollution exist in the forms of petroleum, radioactive substances, and heat.

     Ninety-five percent of all fresh water on earth is ground water

Ground water is found in natural rock formations.

These formations, called aquifers, are a vital natural resource with many uses.  Nationally, 53% of the population relies on ground water as a source of drinking water.  In rural areas this figure is even higher.  Eighty one percent of community water is dependent on ground water.  Although the 1992 Section 305(b) State Water Quality Reports indicate that, overall, the Nation�s ground water quality is good to excellent, many local areas have experienced significant ground water contamination. Some examples are leaking underground storage tanks and municipal landfills.
