Amazing - reptiles the Amazon

The Amazon is filled with danger. Soldier ants march by the millions devouring all life in their path. Submerged up to the eyes, Crocodiles lie in wait for the unwary - whatever or whoever that may be. Undulating its 20-foot length beneath the surface, the Anaconda, one of the world's largest snakes, uses heat-seeking guidance to find its next meal. The barbed stinger in the tail of platter-sized stingrays can inflict a wound that takes months to heal. But none of these carry the fearsome mystique of the voracious Piranha, the perfect killing machine.

The six-pound test line danced like a cat on a hot pavement. All hell had broken loose. Beads of sweat rolled down Doris' back. Her clothes were now a second skin, clinging to her every move.

We panted for breath. We had fish on. The silvery oval-shaped body and red belly of a Piranha broke the surface. I reached for it. "Don't let a finger get near their mouths or you'll lose it", our native guide barked.
Ranging through South America from Brazil to the lowlands of Peru, they also inhabit waters in Venezuela, Guyana, Colombia, Ecuador and Bolivia. In the Amazon and Rio Negro rivers of Brazil and the Orinoco River in Venezuela, no creature is safe from the Piranha's razor-sharp teeth and powerful jaws. The serrated teeth fit together like scissors, enabling Piranha to cut the flesh from their prey. Like a shark, a Piranha's teeth are replaceable, when one breaks off a new one grows in its place.

The Yagua Indians of Peru often use the sharp edges between the teeth of a Piranha jawbone to sharpen the point of their blowgun darts. A fish that is dying or swimming erratically will be quickly attacked by a large school. Piranha will also attack without warning to defend their eggs and territory. A wounded animal that strays into the water will be stripped to the bone so quickly it seems almost to "dance" on the surface as it's ravaged from beneath. A bird that falls into the water will be gone, feathers and all, in three minutes or less. A trapped fish struggling in a net will be chewed clean to the head in a matter of seconds. Attacks on large animals and humans are often dramatically portrayed, but are rare. In some regions Piranha are known as "donkey castrators".
"They will rend and devour alive any wounded man or beast." U.S. President Teddy Roosevelt said, adding, "Piranha are the most ferocious fish in the world." Piranha, also called Caribe or Piraya only furthered their fearsome mystique when Roosevelt encountered them during his exploits in 1914. There are about 35 known species of Piranha but only five species represent a danger to man. Species range from the Red-Belly Piranha (Pygocentrus nattereri) with its characteristic red belly to the largest of the carnivorous species, the Black Piranha with its demon-red eyes and a 17 and a half inch long dark body weighing up to ten pounds. It could remove a man's hand in two or three bites.
Most species dine on fruit or seeds that fall into the water from overhanging trees. The fish are not always aggressive. Women wash clothes in knee-deep water where men spearfish while children bathe or swim in these same Piranha-infested waters without harm. Further adding to the Piranha's mystique, Indian men with half a dozen wives and up to a score of children attribute their potency to Piranha-head soup, although no scientific justification for the soup's potency yet exists.
Piranhas are usually part of indigenous peoples diet in the areas where the fish are found. All you need to go Piranha fishing are lines with a metal leader next to the hook so the fish doesn't bite through the line, a supply of red, raw meat (worms or cut-up fish will do too) and a bit of luck. Piranha swim in large schools and are attracted by movement and blood. In May of 1999, hundreds of anglers armed with rods, reels, and raw steak flocked to the Brazilian town of Aracatuba near Sao Paolo for a one-Sunday piranha fishing tournament. The townspeople had declared open season on the flesh-eating fish, which had decimated other species in the local river. The prize for the tournament was an outboard motor. But "most fishermen were content to go home with plenty of the reputedly aphrodisiac piranha", claimed then town spokesman Nelson Custidio.
Piranha, earning their notorious reputation by reportedly killing 1,200 head of cattle every year in Brazil, is some of the best eating in South America. Whatever name you call them and no matter where you try them, when cooked in a variety of ways, their firm light flesh with its smooth, slightly nutty flavor, is a taste you're sure to enjoy.

Amazing crocodiles

When you holiday in the Northern Territory, it is wise to check with Parks and Wildlife centres to find out where it is safe to get into the water. There are water leisure centres and tours to keep you safe from the saltwater croc. Visit a crocodile park or farm; they allow you to hold a baby croc. They are very soft and cold to the touch. Help feed the small and large crocodiles. Get some great photos. Read the following to find out what you may not know about the 'salty'.
Their teeth are sharp-pointed, inter-locking and are perpetually replaced. A single croc might grow up to 3,000 teeth in its lifetime. How amazing is that? A small bird hops right info the prehistoric estuarine Crocodile's mouth and cleans its teeth.
It is believed the purpose of this is to give them ballast when diving, and are often ingested to aid digestion - crushing food by a grinding action within the gizzard of the stomach. 'Kill two birds with one stone!'

Because Northern Australia has some small, inoffensive crocodiles restricted to brackish or fresh water, most people think all inland crocodiles are freshwater crocodiles. That is very misleading. It can and has lulled people taking great risks in what are now unsafe places as they know the freshwater crocodile to be usually harmless,unless provoked. The saltwater crocodile starts its life in brackish or fresh water, and only travels out to the ocean when it is almost fully grown to search for new territory.
They swim into freshwater tributaries, lagoons, swamps and rivers. Saltwater crocodiles have been known to live there for the rest of their lives. So, do not think that they are only in the ocean.
Their scales are the same substance that hooves and nails are made from; keratin. One of the main functions of crocodile scales is for their protection.

In the breeding season between September to May, the female builds a nest of a scratched up pile of rotting plant matter and mud or sand. She lays about 30 to 90 eggs and covers them with more of the same material. They are incubated for 3 months. The saltwater crocodile lays in the wet season and many nests are destroyed by floodwaters.
When she hears the babies chirping, she digs them out of the nest and carefully carries them to the water's edge in her mouth. She will watch over them until they can look after themselves.
Juvenile crocodiles are eaten by the territorial mature males. Even with the mother's care, only about 20% survive to maturity, as goannas, snakes, sharks, birds and turtles will eat them, also.
All the propulsion and steering comes from the paddling of the flattened tail.
Saltwater crocodiles are now, unfortunately, becoming a public menace as their numbers increase. They have increased in the Northern Territory from about 5,000 to 80,000 in 38 years, and they are moving closer to residential areas.Is it up to us to stay out of their way? After all, these animals held unchallenged dominion over equatorial wetlands and waterways for 65 million years after dinosaurs had gone.
It is the larger crocodile that breeds and it would be these big ones that the crocodile hunter would target. The Parks and Wildlife have taken many large dangerous saltwater crocodiles away from areas that humans also frequent. They have been known to return within a few weeks, unless they are taken to a crocodile farm. It has been said, by interested parties, that even if dozens of crocodiles were culled, how can it be guaranteed that just one crocodile will not come into a proclaimed safe area. It only takes one reptile to kill one person.
